+2004-08-16  Kenichi Handa  <handa@m17n.org>
+
+        * ps-mule.el (ps-mule-font-info-database): Fix docstring.
+
+2004-08-15  Kenichi Handa  <handa@m17n.org>
+
+        * term/x-win.el (x-selection-value): If utf8 was successful but
+        ctext was not, use utf8 string.
+
+2004-08-14  Davis Herring  <herring@lanl.gov>
+
+        * isearch.el: Remove accidental changes of March 4.  Fix backing
+        up when a regexp isearch is made more general.  Use symbolic
+        accessor functions for isearch stack frames to make usage clearer.
+        (search-whitespace-regexp): Made groups in documentation shy (as
+        is the group in the default value).
+        (isearch-fallback): New function, addresses problems with regexps
+        liberalized by `\|', adds support for liberalization by `\}' (the
+        general repetition construct), and incorporates behavior for
+        `*'/`?'.
+        (isearch-}-char): New command, calls `isearch-fallback' with
+        arguments appropriate to a typed `}'.

+        appropriately.

+
+        * battery.el (battery-linux-proc-acpi): Look into battery
+        directories matching the literal string "CMB", too (required for
+        Linux kernel version 2.6.7).
+
+2004-08-14  John Paul Wallington  <jpw@gnu.org>
+
+        * cus-start.el (read-file-name-completion-ignore-case): Add.

+        (speedbar-file-lists): Don't ignore file-name case on Unix and use
+        dolist.
+        (speedbar-insert-files-at-point): Take an extra argument and use
+        it to optionally find out if a subdir is empty.  Also unreadable
+        files don't get expand buttons.
+        (speedbar-directory): New image (unused pixmap already existed).
+        (speedbar-expand-image-button-alist): Use it.
+
+2004-08-11  Martin Stjernholm  <bug-cc-mode@gnu.org>
+
+        CC Mode update to 5.30.9:
+
+        * progmodes/cc-defs.el, progmodes/cc-vars.el (c-emacs-features):
+        Move from cc-vars to cc-defs for dependency reasons.  Fix the
+        POSIX char class test to check that it works in
+        `skip-chars-(forward|backward)' too.
+
+        * progmodes/cc-align.el (c-lineup-arglist): Fix bug when the
+        first argument starts with a special brace list.
+
+        * progmodes/cc-engine.el (c-forward-type): Fix promotion bug
+        when `c-opt-type-concat-key' is used (i.e. in Pike).
+
+        * progmodes/cc-engine.el (c-looking-at-special-brace-list):
+        Fix bug when the inner char pair doesn't have paren syntax, i.e. "(<
+        >)".
+
+        * progmodes/cc-align.el (c-lineup-multi-inher): Made it syntactic
+        whitespace safe.
+
+        * progmodes/cc-engine.el (c-guess-basic-syntax): Fix anchor
+        position for `arglist-intro', `arglist-cont-nonempty' and
+        `arglist-close' when there are two arglist open parens on the same
+        line and there's nothing in front of the first.
+
+        * progmodes/cc-fonts.el (c-basic-matchers-before): Fix font
+        locking of qualified names in Java, which previously could fontify
+        common indexing expressions in many cases.  The standard Java
+        naming conventions are used to tell them apart.
+
+        * progmodes/cc-align.el (c-lineup-whitesmith-in-block):
+        Fix inconsistency wrt opening parens on the first line inside a paren
+        block.
+
+        * progmodes/cc-defs.el (c-langs-are-parametric): Must be known at
+        compile time for the sake of `c-major-mode-is'.
+
+        (c-mode-is-new-awk-p): Made it a macro to delay expansion of
+        `c-major-mode-is' in the event that this is used inside a
+        `c-lang-defconst'.
+
+        * progmodes/cc-defs.el (c-major-mode-is): Fix expansion inside
+        `c-lang-defconst' so that it works better with fallback languages.
+
+        * progmodes/cc-defs.el (c-add-language): Fix a typo that caused
+        it to fail to record the base mode.
+
+        * progmodes/cc-engine.el (c-syntactic-re-search-forward):
+        Fix bug so that it doesn't go past the closing paren when PAREN-LEVEL
+        is used.  Reordered the syntax checks to get more efficient
+        skipping in some situations.
+
+        * progmodes/cc-cmds.el (c-electric-brace): Don't trip up on a line
+        continuation which might precede the newly inserted '{'.
+
+        * progmodes/cc-engine.el (c-syntactic-re-search-forward):
+        Fix cases where it could loop indefinitely.
+
+        * progmodes/cc-fonts.el (c-font-lock-declarators): Handle array
+        size specs correctly.  Only fontify identifiers in front of '('
+        with as functions - don't accept any paren char.  Tightened up
+        initializer skipping to stop before function and class blocks.
+
+        * progmodes/cc-engine.el (c-beginning-of-decl-1): Fix bug where
+        the point could be left directly after an open paren when finding
+        the beginning of the first decl in the block.
+
+        * progmodes/cc-engine.el (c-parse-state): Don't use the syntax
+        table when filtering out legitimate open parens to be recorded.
+        This could cause cache inconsistencies when e.g.
+        `c++-template-syntax-table' was temporarily in use.
+
+        * progmodes/cc-engine.el (c-on-identifier)
+        (c-simple-skip-symbol-backward): Small fix for handling "-"
+        correctly in `skip-chars-backward'.  Affected the operator lfun
+        syntax in Pike.
+
+        * progmodes/cc-engine.el (c-invalidate-sws-region-after):
+        Fix bug that could cause an error from `after-change-functions' when
+        the changed region is at bob.
+
+2004-08-11  Alan Mackenzie  <bug-cc-mode@gnu.org>
+
+        CC Mode update to 5.30.9:
+
+        * progmodes/cc-cmds.el, progmodes/cc-vars.el: Amend doc(-strings)
+        to say that <TAB> doesn't insert WS into a CPP line.
+        (c-indent-command, c-tab-always-indent): Amend doc strings.
+
+        * progmodes/cc-styles.el, progmodes/cc-engine.el: Add in two
+        checks for user errors, thus eliminating cryptic and unhelpful
+        Emacs error messages.  (1) Check the arg to `c-set-style' is a
+        string.  (2) Check that settings to `c-offsets-alist' are not
+        spuriously quoted.
+
+        * progmodes/cc-cmds.el: (c-electric-brace): Don't delete a comment
+        which precedes the newly inserted `{'.
+
+2004-08-10  Michael Albinus  <michael.albinus@gmx.de>
+
+        Sync with Tramp 2.0.44.
+
+        * net/tramp.el (tramp-post-connection): Quote $1 and $2 of shell
+        function "tramp_file_attributes".  Otherwise, file names
+        containing spaces are misinterpreted.  Reported by Magnus Henoch
+        <mange@freemail.hu>.
+        (tramp-handle-file-truename): FILENAME must be expanded first.
+        Otherwise, parameters like "/ssh:deego@gnufans.net:~" will return
+        obscure results.  Reported by D. Goel <deego@gnufans.org>.
+        (tramp-handle-verify-visited-file-modtime): If file does not
+        exist, say it is not modified if and only if that agrees with the
+        buffer's record.  Check whether a file is visiting the buffer, or
+        the buffer has no recorded last modification time.  Return t in
+        case the visiting file doesn't exist.  Suggested by Luc Teirlinck
+        <teirllm@auburn.edu>.
+        (tramp-handle-write-region): Pass modtime explicitely to
+        `set-visited-file-modtime', because filename can be different
+        from (buffer-file-name) if `file-precious-flag' is set.
+        `set-visited-file-modtime' must be called always when `visit' is t
+        or a string.  Suggested by Luc Teirlinck <teirllm@auburn.edu>.
+        (tramp-handle-set-visited-file-modtime): If `time-list' is not
+        nil, don't apply the whole body.  If the file doesn't exists, set
+        modtime to '(-1 65535).  Suggested by Luc Teirlinck
+        <teirllm@auburn.edu>.

+        when built in the Emacs tree.
+
+        * mh-mime.el (mh-identity-pgg-default-user-id): Defvar the

+
+        * mh-seq.el (mh-thread-message, mh-thread-container): Use

+
+        * mh-acros.el (mh-defstruct): New macro which is a partial
+        replacement of the defstruct in CL.
+        (no-byte-compile): Don't compile the file since it isn't loaded at
+        run time, so efficiency isn't an issue.
+
+        * mh-utils.el (mh-buffer-data): Use mh-defstruct instead of

+
+2004-08-09  Satyaki Das  <satyaki@theforce.stanford.edu>
+
+        * mh-funcs.el, mh-junk.el, mh-print.el: Use mh-require-cl to avoid
+        compilation warnings in Emacs-21.3.
+
+        * mh-acros.el (mh-require-cl): Add autoloads of CL functions used.
+
+2004-08-09  Bill Wohler  <wohler@newt.com>
+
+        * mh-customize.el (mh-show-use-xface-flag): Mention that `fetch' and
+        `curl' are supported as well.
+
+2004-08-08  Bill Wohler  <wohler@newt.com>
+
+        * mh-xemacs.el (mh-xemacs-has-toolbar-flag): Checkdoc fixes.
+
+        * mh-mime.el (mh-display-with-external-viewer): Checkdoc fixes.
+
+        * mh-identity.el: (mh-identity-attribution-verb-end): Stripped
+        trailing space; checkdoc fixes.
+
+        * mh-e.el (mh-restore-desktop-buffer): Checkdoc fixes.
+
+        * mh-customize.el: (mh-inc-spool-list,
+        mh-compose-forward-as-mime-flag, defcustom): Stripped trailing
+        space; checkdoc fixes.
+
+        * mh-comp.el (mh-reply): Stripped trailing space.
+
+        * mh-unit.el (mh-unit-files): Added mh-acros.el and mh-gnus.el.
+        (mh-unit): Don't lm-verify pre-21.4. Save buffers before killing
+        since we might have done some editing.
+
+        * import-emacs: Deleted. Functionality subsumed by release-utils.
+
+        * release-utils: New script. Performs import-emacs functionality
+        and displays new and deleted options.
+
+        * Makefile (import-emacs): Call release-utils instead of
+        import-emacs.
+
+        * mh-funcs.el (mh-undo-folder): Removed deprecated `ignore'
+        argument.
+
+        * mh-e.el (mh-scan-date-regexp): Deleted as Peter claims it is

+        `mh-auto-fileds-lists'.
+        (mh-forward-hook): Fixed docstring typo.
+
+2004-08-07  Bill Wohler  <wohler@newt.com>
+
+        * mh-acros.el: New file. Currently holds macros needed by
+        mh-customize.el but is planned to hold all macros to avoid
+        dependency problems when compiling.
+
+        * mh-utils.el (mh-xemacs-flag): Defined in mh-customize.el now.
+        (mh-require-cl, mh-do-in-gnu-emacs, mh-do-in-xemacs)
+        (mh-funcall-if-exists, mh-make-local-hook, mh-mark-active-p):
+        Moved to new file mh-acros.el.
+
+        * mh-customize.el: Require mh-acros and cl only when compiling and
+        mh-loaddefs at runtime instead of mh-utils.
+        (mh-xemacs-flag): Define it here instead of mh-utils.el.

+        is highlighted. The change is needed for this feature to work
+        during folder name completion. This is not entirely sufficient,
+        since the leading "+" in folder names is still mishandled. A patch

+
+        * mh-index.el (mh-indexer-choices): Remove option for the non-free

+        mh-toolbar-init, mh-tool-bar-letter-buttons-set and
+        mh-tool-bar-folder-buttons-set. This enables proper compilation
+        irrespective of whether the XEmacs was built with toolbar support
+        or not.
+
+        * mh-comp.el (mh-letter-mode): Remove conditional since it is not
+        needed.
+
+        * mh-e.el (mh-folder-mode): Same as above.
+

+
+        * mh-xemacs.el (mh-xemacs-icon-map): Remove condition on toolbar
+        presence since we want the build to work if XEmacs without
+        toolbars is used during compilation.

+
+        * mh-customize.el: The Great Reorganization. Sorted groups
+        alphabetically. Aligned variables in customization groups with

+        '-no-autoloads'.
+        (custom-load.elc): Allow for '-no-autoloads'.
+        (compile-xemacs): New.  It allows for the '-no-autoloads' option
+        and byte-compiles all the source files with a single instance of
+        XEmacs. 
+
+        * mh-e.el (mh-folder-mode): Only load the toolbar in XEmacs if
+        toolbar support is available.

+        * mh-comp.el (mh-letter-mode): Only load the toolbar in XEmacs if
+        toolbar support is available.
+
+        * mh-customize.el: Require 'mh-xemacs' at toplevel when
+        'mh-xemacs-flag' is non-nil.
+        Wrap all the toolbar code in a test that is true if using
+        GNU/Emacs or a toolbar-enabled XEmacs.
+
+        * mh-print.el (mh-ps-spool-a-msg): Comment out
+        `clean-message-header-flag' because it isn't used anywhere.

+        * mh-utils.el (mh-show-mode): Only load the toolbar in XEmacs if
+        toolbar support is available.
+
+        * mh-xemacs.el: Autoload `regexp-opt', `customize-group',
+        `view-mode', `with-electric-help', `pp', `sort-numeric-fields',
+        `reverse-region', and `goto-address' at compile time.
+        (mh-xemacs-has-toolbar-flag): New.  This is non-nil when XEmacs
+        has toolbar support.

+
+2003-10-21  Mark D. Baushke  <mdb@gnu.org>
+
+        * mh-identity.el (mh-identity-field-handler): Fields that begin
+        with ":" must have an mh-identity-handler defined or the user
+        gets an error.
+
+2003-10-17  Peter S Galbraith  <psg@debian.org>
+
+        * mh-customize.el (mh-identity-list): This change affects users!
+        The keyword "signature" becomes ":signature".  The recently added
+        keyword "pgg-default-user-id" becomes ":pgg-default-user-id".
+        (mh-auto-fields-list): The keyword "Identity" becomes ":identity".
+        (mh-identity-handlers): Idem for signature and pgg-default-user-id.
+
+        * mh-comp.el (mh-insert-auto-fields): Idem for Identity.
+
+2003-10-17  Peter S Galbraith  <psg@debian.org>
+
+        * mh-xemacs.el: Add eval-and-compile call to (load "toolbar" t t) to
+        make sure `toolbar-make-button-list' is defined.  We can't use
+        require because Emacs doesn't have this library.
+
+2003-10-16  Bill Wohler  <wohler@newt.com>
+
+        * mh-customize.el (mh-signature-file-name)

+        (mh-insert-signature): Merge docstring with manual.
+
+        * mh-customize.el (mh-junk): Changed manual link in defgroup from
+        Customizing mh-e to Junk.
+        (mh-junk-function-alist): Moved SpamAssassin to first in list on
+        the hunch that it is the most popular and should be chosen if
+        other anti-spam programs exist.
+        (mh-junk-mail-folder): Since the variable can accept values other
+        than folder names, renamed to mh-junk-disposition to more
+        accurately reflect the content. Merge docstring with manual.
+        (mh-junk-program): Moved SpamAssassin to the top of the menu for
+        the same reason presented in mh-junk-function-alist. Also, fixed
+        case of spam programs to match official usage. Merge docstring
+        with manual.
+
+        * mh-junk.el (mh-junk-blacklist):
+        s/mh-junk-mail-folder/mh-junk-disposition/. Merge docstring with
+        manual.
+        (mh-junk-whitelist): Merge docstring with manual.
+        (mh-bogofilter-blacklist): No longer suggest using automatic
+        classification so use -s instead of -Ns.
+        (mh-bogofilter-whitelist): No longer suggest using automatic
+        classification so use -n instead of -Sn.
+        (mh-spamassassin-blacklist, mh-spamassassin-whitelist): Merge
+        docstring with manual. Moved spamassassin functions to top of file
+        so functions appear in same order that they are presented in menu.
+
+2003-10-09  Peter S Galbraith  <psg@debian.org>
+
+        * mh-customize.el (mail-citation-hook): Moved from mh-comp.el and

+
+        * mh-comp.el (mh-get-header-field): Add autoload cookie.
+

+
+        * Makefile (MH-E-SRC): Add mh-print.el.
+
+2003-10-07  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-x-image-url-fetch-image): In XEmacs,
+        make-temp-file is not present. So to avoid security problems, use
+        a temporary file in the user's home directory. This avoids issues
+        in creating files in a world-writable directory.
+
+        * mh-mime.el (mh-signature-highlight): In Emacs, arrange for the
+        overlay to be freed when it is no longer needed. Also, implement
+        signature highlighting in XEmacs.
+
+2003-10-05  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-mime.el (mh-mime-display, mh-mm-inline-message): Respect the
+        value of `mm-verify-option' and `mm-decrypt-option'.
+        (mh-mime-display-security): Rearrange code a bit to avoid too many
+        new lines being inserted when message verification/decryption is
+        carried out while the message is being read. Also use the
+        point-m{in|ax}-marker functions to make the function easier to read.
+        (mh-mime-security-press-button): Extend the function so that the
+        user can verify/decrypt messages while reading them.
+
+        * mh-gnus.el (mm-possibly-verify-or-decrypt): Added to avoid
+        compiler warning with old Gnus.
+
+        * mh-utils.el (mh-x-image-url-sane-p): New function which checks
+        if the URL in X-Image-URL is something we can handle.
+        (mh-x-image-url-display): Don't display image if the URL looks
+        malformed.
+
+2003-10-04  Mark D Baushke  <mdb@gnu.org>
+
+        * mh-comp.el (mh-letter-menu): Simplify menu heading.
+
+2003-10-03  Mark D Baushke  <mdb@gnu.org>

+
+        * mh-comp.el (mh-letter-menu): Remove the Disable Security
+        parenthetical comment.
+
+        * mh-loaddefs.el: Regenerated.
+        
+        * mh-customize.el (mh-mml-method-default): What method should be
+        used in secure directives.
+        
+        * mh-mime.el (mh-secure-message): New function used to generate
+        the mml security tags.
+        (mh-mml-unsecure-message): New wrapper function around
+        mml-unsecure-messages.
+        (mh-mml-secure-message-sign-pgpmime): Remove function.
+        (mh-mml-secure-message-encrypt-pgpmime): Ditto.
+        (mh-mml-cryptographic-method-history): New variable.
+        (mh-mml-query-cryptographic-method): New function.
+        (mh-mml-secure-message-encrypt): Ditto.
+        (mh-mml-secure-message-signencrypt): Ditto.
+        (mh-mml-secure-message-sign): Ditto.
+
+        * mh-comp.el (mh-letter-menu, mh-letter-mode-help-messages,

+
+2003-09-26  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-seq.el (mh-interactive-range): The function has been
+        extended so that it now takes a default result to return if no
+        interactive prefix arg is given and no region is active.
+
+        * mh-e.el (mh-add-sequence-notation): If transient-mark-mode is
+        on, then the active region is deactivated based on whether a user
+        sequence or a internal sequence is being notated. The change
+        removes this inconsistency.
+        (mh-catchup, mh-folder-map): A new interactive function to mark
+        messages as read has been added and bound to "F c" in the folder
+        mode.
+
+        * mh-utils.el (mh-show-catchup, mh-show-folder-map): New
+        interactive function callable from show mode buffers has been
+        bound to "F c".

+        (mh-invisible-header-fields-default, mh-invisible-header-fields):
+        Merge docstring with manual.
+
+2003-09-24  Mark D. Baushke  <mdb@gnu.org>
+
+        * mh-junk.el (mh-junk-blacklist): Junked messages should be put
+        into the mh-seen-list to avoid propagating the unseen sequence
+        into the spam folder.
+
+        * mh-loaddefs.el: Regenerated.
+
+        * mh-mime.el (mh-mml-secure-message-sign-pgpmime): Add an optional
+        dontsign argument to remove an existing secure message directive.
+        Update the docstring -- this fuction does not allow for
+        encrypt/sign, just sign directives.
+
+        * mh-mime.el (mh-mml-secure-message-sign-pgpmime): Use
+        mml-insert-tag directly to provide a sender if
+        mh-identity-pgg-default-user-id is set.
+        (mh-mml-secure-message-encrypt-pgpmime): Use mml-insert-tag
+        directly to provide a sender if this message is to be both signed
+        and encrypted and mh-identity-pgg-default-user-id is set.
+
+2003-09-23  Bill Wohler  <wohler@newt.com>
+
+        * mh-alias.el (Commentary): Removed as it is now in the manual.
+        (mh-alias-system-aliases): Moved here from mh-customize.el. By
+        definition, "system" definitions are not user-visible, and user
+        filenames are in the the Aliasfile: profile component, so this
+        variable really shouldn't be a defcustom
+        (mh-alias-tstamp, mh-alias-filenames, mh-alias-reload)
+        (mh-alias-add-alias, mh-alias-grab-from-field)
+        (mh-alias-add-address-under-point, mh-alias-apropos): Merge
+        docstring with manual.
+        (mh-alias-reload-maybe): Minor comment update.
+        (mh-alias-insert-file): Merge docstring with manual. Removed
+        "[press TAB]" from prompt since users should know about completion
+        and space can be used as well.
+        (mh-alias-for-from-p): No longer returns a surprising result (t if
+        there was **not** an alias for the From field) if the From header
+        field is missing. This function now returns what you would expect
+        a function of this name to return. Renamed from
+        mh-alias-from-has-no-alias-p since negatives in the function name
+        make logic harder to follow.
+        (mh-alias-add-alias-to-file): Merge docstring with manual.
+        Improved verbiage of prompt. Aliases are now inserted "[b]efore"
+        or "[a]fter" the existing alias instead of "[i]nsert" or
+        "[a]ppend." Note how the new usage flows better.
+
+        * mh-customize.el (mh-alias): Changed manual link in defgroup from
+        Customizing mh-e to Aliases.
+        (mh-alias-grab-from-field button): mh-alias-from-has-no-alias-p
+        renamed to mh-alias-for-from-p and no longer returns surprising
+        value if there isn't a From field. Therefore, enable button if
+        there is a From header field and mh-alias-for-from-p returns nil.
+        (mh-letter-complete-function)
+        (mh-alias-completion-ignore-case-flag, mh-alias-flash-on-comma)
+        (mh-alias-insert-file, mh-alias-insertion-location)
+        (mh-alias-local-users, mh-alias-local-users-prefix)
+        (mh-alias-passwd-gecos-comma-separator-flag): Merge docstring with
+        manual.
+        (mh-alias-system-aliases): Moved to mh-alias.el.
+
+        * mh-comp.el (mh-letter-complete-function-alist): Removed comment
+        about making this customizable since I didn't think it seemed
+        appropriate in the manual.
+        (mh-letter-complete): Merge docstring with manual.
+
+2003-09-23  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-speed.el (mh-speed-flists): When exiting emacs, don't ask if
+        the flists process should be killed.
+
+        * mh-e.el (mh-folder-message-menu): Enable undo menu entry only
+        if something can be undone.
+
+        * mh-customize.el (undo): Enable undo button only if something

+
+        * mh-identity.el (mh-insert-identity): Modified to use
+        `mh-identity-handlers', adding hacking flexibility for those who
+        might need it.
+        (mh-identity-field-handler): New function. Return the handler for
+        a FIELD or nil if none set. The field name is downcased.
+        (mh-identity-handler-gpg-identity): New function; handler for pgg
+        pgp identities.  It sets a buffer-local value for
+        `mh-pgg-default-user-id' which must be handled by mh-send-letter.
+        (mh-identity-pgg-default-user-id): New buffer-local variable to
+        hold the requested key ID.
+        (mh-identity-handler-signature): New function; handler t insert
+        and remove signature files.

+        trailing colon or not.
+        (mh-identity-make-menu): Add a "Customize Identities" menu entry.
+        
+        * mh-loaddefs.el: Regenerated.

+        GNU mailutils now supports the %(decode) format 
+
+2003-09-20  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-gnus.el (mh-mm-text-html-renderer): New function to query
+        which HTML renderer is being used by Gnus.
+
+        * mh-mime.el (mh-signature-highlight): Renderers used to display
+        HTML parts garble the signature separator in various ways. The
+        function has been modified to take that into account.
+        (mh-mime-display-single, mh-mm-display-part): Pass the new
+        optional argument to `mh-signature-highlight'.

+
+2003-09-18  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-seq.el (mh-toggle-tick): Don't hardcode the name of the tick
+        sequencence in the function. This would have caused improper
+        highlighting of the tick sequence if the user had changed its
+        name.
+

+        * mh-gnus.el (mm-inline-text-vcard): Make vcard display work with
+        Gnus-5.9. The extra file vcard.el is still needed.
+
+        * mh-mime.el (mh-signature-highlight): New function that
+        highlights message signatures.
+        (mh-mm-display-part, mh-mime-display-single): Highlight signatures
+        using `mh-signature-highlight' (closes SF #802722). More work is
+        needed for XEmacs.
+        (mh-mime-display): Highlight signature in non-MIME email too.
+
+        * mh-customize.el (mh-show-signature-face): New face used to

+
+2003-09-08  Peter S Galbraith  <psg@debian.org>
+
+        * mh-e.el (mh-version): Do something sensible when

+        * mh-junk.el (mh-spamassassin-blacklist)
+        (mh-spamassassin-whitelist): Change options to be compatoble with

+
+2003-09-07  Mark D. Baushke  <mdb@gnu.org>
+
+        * mh-mime.el (mh-access-types): Per RFC 2049, the "afs"
+        access-type for message/external-body has been removed.
+        Update the comments to reference the current MIME RFCs
+        2045, 2046 and 2049 rather than the obsolete RFC 1521.

+2003-09-05  Peter S Galbraith  <psg@debian.org>
+

+
+        * mh-utils.el (mh-picon-directory-list, mh-picon-directory): The

+        (mh-picon-existing-directory-list): New variable that contains
+        the list of picon directories that actually exist.
+        (mh-picon-set-directory-list): New function to update
+        mh-picon-existing-directory-list from mh-picon-directory-list.
+        (mh-picon-get-image): The function has been modified to search a
+        list of possible picon source directories. The regexp to extract
+        the username from the email address has been made smarter so that
+        it can recognize email addresses of the form user+random@foo.net
+        and extract "user" from there.

+        (mh-picon-generate-path): The function has been generalized so
+        that searching multiple paths is now feasible.

+        Emacs20 doesn't complain.
+
+        * mh-e.el (mh-colors-available-p): Wrap call to
+        display-color-cells in a mh-funcall-if-exists to avoid compiler
+        warning in Emacs20.
+
+2003-08-25  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-e.el (mh-colors-available-flag, mh-folder-mode): New
+        variable to track if colors are available and it is set
+        appropriately in mh-folder-mode.
+        (mh-colors-available-p, mh-colors-in-use-p): Two functions to
+        check whether colors are available and if they are actually being
+        used.
+        (mh-add-sequence-notation): Just changing a scan line doesn't
+        make font-lock refontify the line in Emacs20. So explicitly
+        refontify the scan line in such a situation.
+        (mh-internal-seq): If colors aren't being used then treat the
+        tick sequence like a normal user sequence.
+
+        * mh-seq.el (mh-put-msg-in-seq): Do font-lock highlighting after
+        the messages have been added to the sequence.
+        (mh-toggle-tick): Modified so that highlighting of the ticked
+        messages will be properly done. If font-lock isn't being used or
+        if colors aren't supported by the Emacs where MH-E is running,
+        then the `%' character is used to annotate ticked messages.
+
+        * mh-utils.el (mh-picon-image-types): Since Emacs20 doesn't have
+        image-type-available-p, wrap calls to that function in
+        ignore-errors.
+        (mh-add-msgs-to-seq): Do the font-lock highlighting after the
+        messages have been added.

+
+        * mh-e.el: Don't require mh-xemacs-compat which no longer exists.
+        The XEmacs stuff gets required by mh-customize.el which is
+        required by mh-utils.el which is required by mh-e.el. This all
+        happens before mh-xemacs-compat was required, so all should be
+        well.
+
+        * mh-unit.el (mh-unit-files): Replaced mh-xemacs-compat.el and
+        mh-xemacs-icons.el with mh-xemacs.el.
+
+        * mh-xemacs.el: New file from concatenation of mh-xemacs-compat.el

+
+        * mh-customize.el (mh-compose-skipped-header-fields): Use

+        (mh-index-ticked-messages-folders): Since mh-tick-seq is
+        customizable, use it instead of tick in the docstring.
+
+        * mh-index.el (mh-index-ticked-messages): Since mh-tick-seq is
+        customizable, use it instead of tick in the docstring.

+        (mh-narrow-to-tick): Since mh-tick-seq is customizable, use it
+        instead of tick in the docstring. Also, use mh-tick-seq instead of
+        tick in warning message.
+
+2003-08-20  Peter S Galbraith  <psg@debian.org>

+        * mh-customize.el: setq mh-variant to 'none when byte-compiling,

+
+        * mh-init.el (mh-variant-set): Don't probe for MH variant when

+
+2003-08-19  Peter S Galbraith  <psg@debian.org>
+
+        * mh-pick.el (mh-pick-single-dash): New defconst.  Search

+
+        * mh-seq.el: (mh-edit-pick-expr): Renamed from mh-read-pick-regexp
+        since the new name is more indicative of what the function does.
+        Prompt now says "Pick expression" instead of "Pick regexp".
+        (mh-narrow-to-subject): Rewrote function to behave like other
+        similar functions.
+        (mh-narrow-to-header-field, mh-narrow-to-range)

+
+        * mh-customize.el (mh-auto-fields-list): The manual uses Fcc
+        instead of fcc, so I've changed the user-visible text
+        accordingly. I've left the const alone for backwards
+        compatibility.
+
+2003-08-14  Bill Wohler  <wohler@newt.com>
+
+        * mh-identity.el (mh-insert-identity): Changed signature deletion
+        test to test for both markers, rather than testing to see if the
+        start marker is bound. Since the start marker is defined in this
+        file, it should always be bound. Suggestion by Satyaki.
+
+        * mh-comp.el (mh-send-letter): Go to the top of the draft so that
+        the user can see which header fields have been inserted. I think
+        this is more important than leaving point alone or going to the
+        end to see the signature since Mail-Followup-To or Bcc or cc could
+        have some deleterious effects.
+
+        * mh-customize.el (mh-auto-fields-prompt-flag): New variable.
+        Non-nil means to prompt before sending if fields inserted.
+
+        * mh-comp.el (mh-insert-auto-fields): Now return t if fields
+        inserted; otherwise nil.
+        (mh-send-letter): Deleted obsolete documentation about adding
+        X-Mailer and X-Face. Prompt before sending if auto fields added
+        and mh-auto-fields-prompt-flag is t.
+
+        * mh-customize.el (mh-identity-list): Allow signature to come from
+        mh-signature-file-name. In this case, the "signature" value is set
+        to nil. This might not be the best implementation. Suggestions
+        welcome.
+
+        * mh-identity.el (mh-insert-identity): Now that the signature can
+        be a nil value, moved test higher up in cond so that the test for
+        a nil value would not be executed first prevening signature
+        handling. Handle nil signature value by calling
+        mh-insert-signature with no arguments which means to use
+        mh-signature-file-name.
+
+        * mh-comp.el (mh-insert-signature): Changed text of message if no
+        signature inserted.
+
+        * mh-customize.el (mh-identity-list): Changed "Signature" constant
+        back to "signature" so it *won't* be backwards-incompatible any
+        more. I discovered one could use the :tag keyword to get headline
+        captalization in the menu.
+
+        * mh-identity.el (mh-insert-identity): Ditto.
+
+        * mh-identity.el (mh-identity-make-menu): Always build menu.
+        Always create Insert Auto Fields menu item. Just don't enable it
+        if mh-auto-fields-list is nil. Enable radio buttons always. Make
+        None a radio button choice with the other identities.
+
+        * mh-comp.el (mh-letter-menu): Removed cond on fboundp
+        'easy-menu-define. We don't do this elsewhere.
+
+2003-08-13  Bill Wohler  <wohler@newt.com>
+
+        * mh-identity.el (mh-identity-make-menu, mh-insert-identity): Use
+        headline capitalization in menu items. Even the internal names are
+        exposed in the customize interface, so they need to be uppercase
+        too.
+        (mh-insert-identity): Rather than goto-char to
+        mh-identity-signature-start before deleting, simply pass it to
+        delete-region. When setting markers, use point-min-marker and
+        point-max-marker instead of moving point. Set marker type of
+        mh-identity-signature-start to t to fix a bug where changing
+        identity deleted user's text.
+
+        * mh-customize.el (mh-identity-list, mh-auto-fields-list):
+        Reworked docstring. Use headline capitalization. Commented out
+        implementation details for later deletion or resurrection upon
+        popular demand. N.B. If your mh-identity-list contains "signature"
+        then you will need to either edit your .emacs file manually, or
+        delete your existing "signature" which will become a regular field
+        with this change and create a new signature. I figured I could get
+        away with this since 8.0 is a major release, and coinciding with
+        the manual update will be a MAJOR release. I apologize profusely
+        that I didn't catch this before it was released.
+        (mh-identity-default): Use headline capitalization in example.
+
+2003-08-12  Jeffrey C Honig  <jch@honig.net>

+        file didn't exist, an fboundp error was thrown. This was fixed by
+        removing signature tests that were redundant and out of date with
+        the tests in mh-insert-signature. Removed second signature
+        condition as it is now handled in the first signature condition.
+
+2003-08-12  Peter S Galbraith  <psg@debian.org>
+
+        * mh-identity.el (mh-insert-identity): Don't insert new lines on
+        signatures anymore.
+
+        * mh-comp.el (mh-insert-signature): Make sure signature file is
+        readable before trying to insert it.
+
+2003-08-11  Bill Wohler  <wohler@newt.com>
+
+        * mh-comp.el (mh-insert-signature): Unconditionally insert a
+        newline so that signatures are inserted consistently, and so that
+        there isn't any text after the cursor so that the user can start
+        typing his message immediately. Use new variable and function
+        mh-signature-separator and mh-signature-separator-p.
+
+        * mh-customize.el (mh-delete-yanked-msg-window-flag): Checkdoc
+        fix.
+        (mh-signature-file-name): Updated docstring now that this variable
+        can be a function. Added cross-references to
+        mh-signature-separator, mh-signature-separator-regexp, and
+        mh-signature-separator-p which might be used in such functions.
+
+        * mh-identity.el (mh-insert-identity): Don't include signature if
+        signature separator already present. Useful when running
+        mh-edit-again.
+
+        * mh-mime.el (mh-inline-vcard-p): Use mh-signature-separator-p.
+
+        * mh-utils.el (mh-signature-separator-regexp): New variable
+        containing "^-- $" which should be used when looking for the
+        signature separator.
+        (mh-signature-separator): New variable containing "-- \n" which
+        should be used when inserting the signature separator.
+        (mh-signature-separator-p): New function that returns non-nil if
+        mh-signature-separator-regexp is found in the buffer.
+
+2003-08-09  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-x-image-scaling-function): Variable that
+        contains function used to scale images. Possible choices are
+        mh-x-image-scale-with-convert and mh-x-image-scale-with-pnm.
+        (mh-convert-executable): Removed.
+        (mh-x-image-scale-with-pnm, mh-x-image-scale-with-convert): New
+        functions that scale images using pnm tools or ImageMagick.
+        (mh-x-image-scale-and-display, mh-x-image-url-display): Use
+        mh-x-image-scaling-function instead of mh-convert-executable.
+
+2003-08-08  Peter S Galbraith  <psg@debian.org>
+
+        * mh-comp.el (mh-insert-signature): Bug fix.  Handle case of nil
+        `mh-signature-file-name' and hooks correctly.
+
+        * mh-identity.el (mh-insert-identity): Refactor to use
+        mh-insert-signature
+        
+        * mh-comp.el (mh-signature-separator-p): Removed.
+
+        * mh-comp.el (mh-insert-signature): Merge MIME awareness from
+        mh-insert-identity into this command. Allow
+        `mh-signature-file-name' to be a function to call.  See if "-- "
+        needs to be inserted only after hooks have run.
+
+2003-08-07  Bill Wohler  <wohler@newt.com>
+
+        * mh-customize.el (mh-compose-skipped-header-fields): Added
+        X-Image-URL.
+        (mh-autoload): Removed cookies. They aren't necessary in
+        mh-e.el, mh-utils.el, or mh-customize.el.
+
+        * mh-e.el (mh-autoload): Removed cookies. They aren't necessary in
+        mh-e.el, mh-utils.el, or mh-customize.el.
+
+        * mh-identity.el (mh-insert-identity): Made regexp for signature
+        separator more explicit. Hmmm, maybe we should create
+        mh-signature-separator-regexp...
+
+        * mh-index.el (mh-replace-string): Moved to mh-utils.el.
+
+        * mh-utils.el (mh-replace-string): Moved here from mh-index.el.
+        (mh-autoload): Removed cookies. They aren't necessary in mh-e.el,
+        mh-utils.el, or mh-customize.el.
+
+        * mh-comp.el (mh-insert-signature): Added file argument to insert
+        a file other than mh-signature-file-name. Insert signature
+        separator, unless file already contains one.
+
+2003-08-06  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-e.el (mh-folder-size, mh-folder-size-folder)
+        (mh-folder-size-flist): If flist is not present use folder to
+        find the number of messages in the folder. Also the .mh_sequences
+        file is read to find the number of unseen messages.
+
+        * mh-utils.el (mh-flists-present-flag, mh-find-progs): Introduce
+        a new variable to test for the presence of the flists program and
+        set it in mh-find-progs.
+
+2003-08-06  Peter S Galbraith  <psg@debian.org>
+
+        * mh-customize.el: Change the order of `mh-identity-list' and
+        `mh-auto-fields-list' and remove byte-compilation defvar for
+        `mh-identity-list'.  This fixes a customization bug for
+        `mh-identity-list', where it wasn't set correctly.
+
+        * mh-identity.el (mh-identity-make-menu): mh-auto-fields-list may
+        not be bound yet when initially loaded.
+
+2003-08-06  Bill Wohler  <wohler@newt.com>
+
+        * mh-alias.el (mh-alias-add-address-under-point): Removed trailing
+        period from messages. The conventions say that errors should not
+        end with a period and that "Foo...done" messages should not end in
+        a period, but they aren't explicit about messages in general.
+        Given what the conventions *do* say, and because most of our
+        messages don't end with a period, let's just say that messages in
+        general don't end in a period, just like error messages.
+
+        * mh-comp.el (mh-extract-rejected-mail, mh-letter-mode-message):
+        Ditto.
+
+        * mh-e.el (mh-refile-a-msg):  Ditto.
+
+        * mh-funcs.el (mh-undo-folder): Ditto.
+
+        * mh-mime.el (mh-mime-save-parts): Ditto.
+        
+        * mh-seq.el (mh-subject-to-sequence-unthreaded) 
+        (mh-narrow-to-subject, mh-delete-subject): Ditto.
+
+        * mh-index.el (mh-index-sequenced-messages)
+        (mh-index-new-messages, mh-index-ticked-messages): Discovered that
+        in general we should only use question marks in yes-or-no-p or
+        y-or-n-p prompts, but not in other prompts that use
+        completing-read and offer defaults. In these cases, use colons
+        instead (closes SF #730470).
+
+        * mh-mime.el (mh-mime-save-parts): Ditto.
+
+        * mh-utils.el (mh-prompt-for-folder): Ditto.
+
+        * mh-alias.el (mh-alias-apropos): Multiple messages are usually
+        shown one at a time rather than appended. Send output to
+        mh-aliases-buffer instead of *Help*.
+        (mh-alias-local-users): Checkdoc fix.
+
+        * mh-funcs.el (mh-undo-folder): Removed commented-out code since
+        its deadline had expired.
+
+        * mh-utils.el (mh-aliases-buffer): New buffer name, used in
+        mh-aliases.el.
+
+2003-08-06  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-x-image-url-cache-canonicalize): Make this
+        function work for XEmacs too.
+        (mh-collect-folder-names): Use folders instead of flists. One
+        advantage is that folders is available on MH while flists is not.
+        Another is that if an explicit -sequence argument isn't given and
+        Unseen-Sequence profile is not present then flists croaks while
+        folders doesn't.
+        (mh-collect-folder-names-filter): Don't consider folder names that
+        start with a `.' character. This is needed since the folders
+        command doesn't filter them out like flists does.
+
+        * mh-index.el (mh-replace-string): Add autoload for it.
+
+2003-08-05  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-mime.el (mh-compose-forward, mh-mhn-compose-forw)
+        (mh-mml-forward-message): The variable mh-sent-from-msg can be a
+        list. So check that the value is really a number before using it
+        like one.
+
+        * mh-comp.el (mh-insert-letter): Same as above.
+
+        * mh-utils.el (mh-picon-get-image): Make the code that finds the
+        address of the sender more robust.
+        (mh-face-display-function): Make it work with XEmacs.
+        (mh-picon-image-types): A new variable that stores what image
+        types can be used.
+
+2003-08-05  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-customize.el (mh-tool-bar-define): Make the save button such
+        that is activated only if the buffer needs to saved.
+
+        * mh-utils.el (mh-face-display-function, mh-picon-get-image): Some
+        domains, for instance cs.cmu.edu, don't have xpm files. So we need
+        to search for all three files. The change does that.
+        (mh-picon-file-contents): A utility function to return the
+        contents of a file as a string.
+        (mh-picon-get-image): Write it as a loop to make it simpler.
+        (mh-x-image-set-download-state): Make the link simpler.
+
+2003-08-04  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-x-image-url-display): Don't bother to try to
+        download image if we don't have the necessary tools to display
+        it.
+        (mh-face-display-function): Add preliminary support for "domain"
+        picons.
+        (mh-picon-get-image, mh-picon-generate-path): Functions to find
+        best match for domain in the From header field.
+
+        * mh-e.el (mh-previous-unread-msg): If some of the messages in the
+        unseen sequence are not present in the folder buffer then calling
+        this function gets stuck and can't skip over them. The change
+        fixes this.
+        (mh-next-unread-msg): Same as above.
+
+2003-08-04  Bill Wohler  <wohler@newt.com>
+
+        * mh-utils.el (mh-show-mode): Added cross reference to
+        mh-folder-mode in docstring (closes SF #728638). Added
+        \\{mh-show-mode-map} to show keymap.
+
+        * mh-e.el (mh-folder-mode): Added information about ranges to
+        docstring (closes SF #728638).
+
+        * mh-speed.el (mh-speed-refresh): New function that calls
+        mh-speed-flists and mh-invalidate-map.
+        (mh-folder-speedbar-key-map): Replaced keybindings for
+        mh-speed-invalidate-map and mh-speed-flists with a single binding
+        for mh-speed-refresh.
+        (mh-folder-speedbar-menu-items): Replaced menu items for Run
+        Flists and Invalidate Cached Folders with the single menu item
+        Refresh Speedbar in order to simplify the UI.
+
+        * mh-customize.el (mh-fetch-x-image-url): Added DOS as another
+        reason not to set this to t.
+
+2003-08-04  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-e.el (mh-scan-folder): Handle ranges from user input properly.
+
+2003-08-03  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-find-msg-get-num): Removed. If threading isn't
+        present, the messages are sorted by index. So `mh-goto-msg' was
+        implemented as a binary search and this function was used in that
+        implementation. So this isn't needed any more.
+        (mh-msg-search-pat): Removed. Before the advent of message
+        threading, this function was used to generate a regexp used to
+        search for a particular message. It isn't used anymore. The
+        variable `mh-scan-msg-number-regexp' should be updated and used in
+        `mh-goto-msg' instead of hardcoding the regexp in the code. Then
+        we might be able to better support other scan line formats in the
+        future.
+
+        * mh-seq.el (mh-map-to-seq-msgs, mh-notate-seq): Removed. These
+        functions were used to notate user sequences. But calling
+        `mh-goto-msg' inside of a loop is inefficient. So the sequence
+        notation code was rewritten thereby making these functions
+        redundant.
+        (mh-copy-line-to-point): Removed. This function was used in the
+        implementation the now removed function `mh-copy-seq-to-point'.
+        That function was problematic and was replaced by the less general
+        `mh-copy-seq-to-eob'. This makes `mh-copy-line-to-point'
+        redundant.
+        (mh-region-to-msg-list): Removed since this is a special case of
+        the more general `mh-range-to-msg-list'.
+
+        * mh-loaddefs.el: Regenerated.
+
+2003-08-03  Jeffrey C Honig  <jch@honig.net>
+
+        * mh-customize.el (mh-invisible-header-fields-default): Added
+        several new fields to hide.  Sorted the list with sort-lines.
+
+2003-08-03  Peter S Galbraith  <psg@debian.org>
+
+        * mh-customize.el (mh-invisible-headers): Variable renamed to
+        `mh-invisible-header-fields-compiled'.
+        (mh-invisible-headers): Implement above change.
+
+        * mh-utils.el (mh-display-msg): Idem.
+
+        * mh-mime.el (mh-mm-inline-message): Idem.
+
+        * mh-comp.el (mh-insert-letter): Idem.
+
+2003-08-03  Bill Wohler  <wohler@newt.com>
+
+        * mh-speed.el (mh-folder-speedbar-menu-items): Added separator
+        between standard and MH-E menu items. Use headline capitalization
+        in menu items.
+
+        * mh-utils.el (mh-temp-fetch-buffer): New constant to hold
+        buffer name for wget output.
+        (mh-x-image-url-fetch-image): Use mh-temp-fetch-buffer instead
+        of hard-coded buffer name. Use make-temp-file to avoid race
+        conditions and subsequent security issues raised in make-temp-name
+        docstring.
+
+2003-08-03  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-wget-executable, mh-wget-choice, mh-wget-option)
+        (mh-x-image-url-fetch-image): Support the use of `curl' and
+        `fetch' as alternatives to `wget'.
+        (mh-wget-choice): Change order of search.
+        (mh-x-image-url-fetch-image): Rename buffer.
+
+2003-08-03  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-x-image-set-download-state)
+        (mh-x-image-get-download-state): Specially named symbolic links
+        are used to keep track of whether a X-Image-URL header field needs
+        to downloaded the next time it is seen. These functions get and
+        set the symlinks appropriately.
+        (mh-x-image-url-fetch-image): Simplified since the query has been
+        moved to `mh-x-image-url-display'. Also if wget isn't present then
+        try again next time since the user might install wget before
+        trying once more.
+        (mh-x-image-scale-and-display): Handle absence of the `convert'
+        program better. If it isn't present then we will try to display
+        the image the next time it is encountered. Also use the -geometry
+        option to convert since the -resize option isn't present in older
+        versions.
+        (mh-x-image-url-display): Move all the code that decides whether
+        an X-Image-URL header field will be fetched in this function. Also
+        remember the user's decision so that if the image couldn't be
+        fetched the first time, we will try to fetch it later on without
+        asking again.
+
+2003-08-02  Peter S Galbraith  <psg@debian.org>
+
+        * mh-alias.el (mh-alias-local-users): Exclude all aliases already
+        in mh-alias-alist from `ali' (closes SF #772595).
+
+2003-08-01  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-x-image-display, mh-x-image-url-display): Avoid
+        a race. The X-Image-URL is displayed asynchronously. Suppose a
+        message with a image is shown with `mh-show'. If a different
+        message is displayed before the image can be fetched, then the new
+        message will have the image displayed. With this change the race
+        is less likely to happen.
+
+2003-08-01  Peter S Galbraith  <psg@debian.org>
+
+        * mh-inc.el (mh-inc-spool-map): Fix what `mh-inc-spool-map-help'
+        must look like as a fake `mh-help-messages' in order to work
+        correctly in mh-help.
+
+2003-07-31  Bill Wohler  <wohler@newt.com>
+
+        * mh-inc.el (mh-inc-spool-map): Use mh-help instead of
+        mh-ephem-message in order to display help in its own buffer
+        instead of minibuffer.
+
+        * mh-utils.el (mh-help-buffer): New variable to hold the name of
+        the MH-E help buffer name.
+
+        * mh-funcs.el (mh-help, mh-prefix-help): Use with-electric-help to
+        display help messages. I observed a friend with a vision
+        disability and the 5 seconds the help appeared on the screen was
+        not long enough for him to lock on it. I've therefore changed the
+        help function to display the help in its own buffer called *MH-E
+        Help* (closes SF #493740 and SF #656631).
+
+        * mh-customize.el (mh-fetch-x-image-url): Changed default from nil
+        to 'ask. Updated docstring from manual.
+        (mh-invisible-header-fields-internal): Added X-Image-URL.
+        (mh-show-use-xface-flag): Updated docstring from manual.
+        (mh-x-face-file): Ditto.
+
+        * mh-mime.el (mh-mhn-compose-external-type): Don't insert the
+        directory parameter if it's nil. The mhbuild man page indicates
+        that this parameter is optional, so this should be fine.
+
+        * mh-comp.el (mh-letter-mode-map): Added keybindings for
+        mh-mhn-compose-anon-ftp and
+        mh-mhn-compose-external-compressed-tar.
+        (mh-letter-menu): Uncommented menu items for same.
+
+2003-07-30  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-loaddefs.el: Regenerated.
+
+        * mh-pick.el (mh-do-pick-search): Removed since the function
+        `mh-pick-do-search' performs the same action as this function.
+
+        * mh-index.el (mh-index-update-unseen): Removed since the
+        generalized sequence synchronization code that keeps sequences in
+        index folders in sync with the sequences in the source folders
+        makes this function redundant.
+
+        * mh-e.el (mh-folder-unseen-seq-name, mh-folder-unseen-seq-list):
+        Removed. These two functions were used in the unseen sequence
+        highlighting before the sequence highlighting code was
+        generalized. In any event calls to the function
+        `mh-folder-unseen-seq-name' can be replaced by the variable
+        `mh-unseen-seq' and calls to `mh-folder-unseen-seq-list' can be
+        replaced with (cdr (assoc mh-unseen-seq mh-seq-list)).
+        (mh-unmark-all-headers): Removed since this function has been
+        superseded by mh-remove-all-notation.
+        (mh-map-over-seqs): Removed since we now have the generalized
+        iteration over message ranges (the `mh-iterate-on-range' macro)
+        that can be used instead.
+        (mh-notate-if-in-one-seq): Removed. This function was used for
+        changing the `%' notation for user sequences. It can't be used for
+        that purpose any more, since we have a different scheme now.
+
+        * mh-unit.el (mh-unit-tests): Removed since it isn't needed any
+        more.
+        (mh-unit): Run all function that start with the string
+        "mh-unit-test-".
+

+        * mh-customize.el (mh-invisible-header-fields): Checkdoc fix.
+
+        * mh-utils.el (mh-x-image-url-cache-canonicalize): Shortened using
+        example in files.el:make-backup-file-name-1.
+        (mh-face-display-function): Added X-Image-URL to docstring.
+
+        * mh-unit.el (mh-unit-x-image-url-cache-canonicalize): New
+        function to test mh-x-image-url-cache-canonicalize since it lent
+        itself well to unit testing. Had to start somewhere!
+        (mh-unit-equal): New function that throws an error if RESULT
+        doesn't equal EXPECTED.
+        (mh-unit): Call mh-unit-x-image-url-cache-canonicalize.
+        
+2003-07-29  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-unit.el (mh-unit-update-call-graph): Make the function work
+        better with dotted lists, that is lists of the form (a b c . d)
+        where `d' isn't nil. With this we are able to avoid marking some
+        functions as unused even though they are actually used in alists.
+
+2003-07-28  Peter S Galbraith  <psg@debian.org>
+
+        * mh-comp.el (mh-insert-letter):  Remove `mh-visible-headers'
+        operation.
+
+        * mh-mime.el (mh-mm-inline-message): Same.
+
+        * mh-utils.el (mh-display-msg): Same.
+        (mh-clean-msg-header): Make a note of above change.
+
+        * mh-customize.el (mh-invisible-header-fields-internal): Renamed
+        from prior `mh-invisible-header-fields-default'.
+        (mh-invisible-header-fields-default): Renamed from prior
+        `mh-invisible-header-fields-default-override'.
+        (mh-invisible-header-fields): Renamed from prior
+        `mh-invisible-header-fields-user'.
+        (mh-visible-headers): Removed!  We use invisible fields only now.
+        (mh-visible-header-fields): Removed!
+
+2003-07-28  Peter S Galbraith  <psg@debian.org>
+
+        * mh-customize.el (mh-invisible-header-fields-default): Added 3
+        new fields to hide.
+
+2003-07-28  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-show): Add an extra argument to the function so
+        that interactive use will always force redisplay of the message.
+
+        * mh-mime.el (mh-mime-display, mh-mm-inline-message): Bind the
+        variables `mm-verify-option' and `mm-decrypt-option' so that
+        verification and decryption of mail can happen without any
+        additional tinkering.
+
+2003-07-25  Peter S Galbraith  <psg@debian.org>
+
+        * mh-customize.el (mh-invisible-header-fields-default): New defvar
+        holding default fields to hide.  This replaces the old
+        `mh-invisible-header-fields' defcustom.
+        (mh-invisible-header-fields-user): New defcustom.  Users add
+        fields to suppress that we didn't include in
+        `mh-invisible-header-fields-default'.  This could be named simply
+        `mh-invisible-header-fields' and it wouldn't really break anything
+        for users who have customized it to a long list now redundant with
+        `mh-invisible-header-fields-default'.
+        (mh-invisible-header-fields-default-override): New defcustom.
+        Users check off the fields they want displyed from what we
+        included in `mh-invisible-header-fields-default'.
+        (mh-invisible-headers): Function adapted to new variables.
+
+2003-07-25  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-e.el (mh-inc-folder): If the user is in a different folder
+        displaying a message and runs mh-inc-folder, then the folder
+        changes to +inbox but the show window continues to display the
+        message in the old folder. The change fixes this.
+        (mh-visit-folder): Make the handling of the show window similar to
+        that of mh-inc-folder.
+
+2003-07-24  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-e.el (mh-folder-message-menu, mh-folder-folder-menu): Use the
+        predicate mh-outstanding-commands-p instead of its exapansion.
+        Also use the same label in both menus.
+        (mh-outstanding-commands-p): Generalized so that it will work in
+        mh-show-mode buffers as well.
+
+        * mh-customize.el (mh-tool-bar-define): Enable tool-bar button for
+        mh-execute-commands only if there are pending deletes or refiles.
+
+2003-07-19  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-utils.el (mh-show-msg): If a unseen message is first marked
+        for deletion/refiling and then displayed, the bold highlighting
+        does not go away. This change fixes that.
+
+        * mh-seq.el (mh-msg-is-in-seq): Fix a bug in the function. If any
+        message was marked for refiling, then the function would have you
+        believe that every message in the folder is being refiled.
+
+2003-07-17  Bill Wohler  <wohler@newt.com>
+
+        * mh-e.el: Removed email address for Stephen Gildea's in Change
+        Log at his request (damn spammers). Removed other email addresses
+        while I was at it since the SourceForge URL should be sufficient
+        contact information.
+
+        (mh-scan-format-*mh): Fixed typo in comment above these variables.
+        These variables are used if mh-scan-format-file is t, not nil.
+        Also mh-scan-format-file is no longer "above" (courtesy Stephen
+        Gildea).
+
+2003-07-17  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-mime.el (mh-mhn-quote-unescaped-sharp): New function that
+        quotes `#' characters in the first column that aren't part of a
+        MHN directive.
+        (mh-mhn-directive-present-p): Generalized to allow the function
+        to search for MHN directives in a part of the buffer.
+        (mh-edit-mhn): Quote unescaped `#' characters in the draft (closes
+        SF #762464).
+
+2003-07-16  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-alias.el (mh-alias-read-address-map): If
+        mh-alias-flash-on-comma is nil when mh-alias is loaded, then
+        setting mh-alias-flash-on-comma to t later on doesn't turn on
+        address completion display till Emacs is restarted. The change
+        fixes this.
+
+2003-07-15  Bill Wohler  <wohler@newt.com>
+
+        * mh-utils.el (mh-cmd-note): Cleaned up docstring (changed phrase
+        to sentences). Moved to Scan Line Formats section.
+        (mh-scan-msg-number-regexp)
+        (mh-scan-msg-overflow-regexp, mh-scan-msg-format-regexp)
+        (mh-scan-msg-format-string, mh-scan-msg-search-regexp): Cleaned up
+        docstrings (changed phrases to sentences).
+        (mh-note-seq): Cleaned up docstring (changed phrase to sentences).
+        Also, this variable is now a character and not a string. Moved to
+        Scan Line Formats section.
+
+        * mh-funcs.el (mh-note-copied, mh-note-printed): Cleaned up
+        docstrings (changed phrases to sentences). Also, these variables
+        are now characters and not strings.
+
+        * mh-e.el (mh-scan-format-mh, mh-scan-format-nmh): Filled. I was
+        hoping to quote the hint `t' but checkdoc wouldn't let me.
+        (mh-note-deleted, mh-note-refiled, mh-note-cur): Moved to Scan
+        Line Formats section.
+        (mh-scan-good-msg-regexp, mh-scan-deleted-msg-regexp) 
+        (mh-scan-refiled-msg-regexp, mh-scan-valid-regexp) 
+        (mh-scan-cur-msg-number-regexp, mh-scan-date-regexp) 
+        (mh-scan-rcpt-regexp, mh-scan-body-regexp) 
+        (mh-scan-subject-regexp, mh-scan-format-regexp): Cleaned
+        up docstrings (changed phrases to sentences).
+        (mh-scan-cur-msg-regexp): Marked this variable as obsolete; it
+        should be removed for 8.0.
+
+        * mh-comp.el (mh-note-repl, mh-note-forw, mh-note-dist): Cleaned
+        up docstrings (changed phrases to sentences). Also, these
+        variables are now characters and not strings.
+
+2003-07-15  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-index.el (mh-index-update-single-msg)
+        (mh-index-create-sequences): Handle the situation where there are
+        copies of the exact same message correctly.
+
+2003-07-15  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-seq.el (mh-thread-update-scan-line-map): Modified since
+        notation is already a character.
+
+        * mh-utils.el (mh-note-seq): Convert from string to character.
+        (mh-notate): Modified since characters are used to notate instead
+        of strings of length one.
+
+        * mh-comp.el (mh-note-repl, mh-note-forw, mh-note-dist): Convert
+        from string to characters.
+
+        * mh-e.el (mh-note-deleted, mh-note-refiled, mh-note-cur): Same as
+        above (closes SF #770772).
+        (mh-unmark-all-headers): Modified since mh-note-* variables are
+        now characters.
+        (mh-remove-sequence-notation): The mh-notate function remembers
+        the previous notation. Before the change to the mh-note-*
+        variables, mh-notate would only remember the change if a string
+        was used to notate the message. Now mh-notate is always called
+        with a character notation. So the deletion has to take place
+        explicitly.
+
+2003-06-28  Bill Wohler  <wohler@newt.com>
+
+        * mh-mime.el (mh-mhn-directive-present-p): If shell comments are
+        present that have a space after the # but no content, then this
+        function would throw an error. This has been fixed (closes SF
+        #762458).
+
+2003-06-27  Satyaki Das  <satyakid@stanford.edu>
+
+        * mh-index.el (mh-index-search): Use the new and improved
+        mh-index-new-folder.
+        (mh-index-new-folder): Improved so that redoing the same search
+        will reuse the old index folder.
+        (mh-index-folder-search-regexp): New function which that extracts
+        out the search expression that produced the index folder.
+
+2003-06-24  Bill Wohler  <wohler@newt.com>
+
+        * mh-e.el (Version, mh-version):  Set to 7.4.1+cvs.

 ;;; Commentary:
 
-;;  [To be deleted when documented in MH-E manual.]
-;;
-;;  This module provides mail alias completion when entering addresses.
-;;
-;;  Use the TAB key to complete aliases (and optionally local usernames) when
-;;  initially composing a message in the To: and Cc: minibuffer prompts. You
-;;  may enter multiple addressees separated with a comma (but do *not* add any
-;;  space after the comma).
-;;
-;;  In the header of a message draft, use "M-TAB (mh-letter-complete)" to
-;;  complete aliases. This is useful when you want to add an addressee as an
-;;  afterthought when creating a message, or when adding an additional
-;;  addressee to a reply.
-;;
-;;  By default, completion is case-insensitive. This can be changed by
-;;  customizing the variable `mh-alias-completion-ignore-case-flag'. This is
-;;  useful, for example, to differentiate between people aliases in lowercase
-;;  such as:
-;;
-;;    p.galbraith: Peter Galbraith <GalbraithP@dfo-mpo.gc.ca>
-;;
-;;  and lists in uppercase such as:
-;;
-;;    MH-E: MH-E mailing list <mh-e-devel@lists.sourceforge.net>
-;;
-;;  Note that this variable affects minibuffer completion only. If you have an
-;;  alias for P.Galbraith and type in p.galbraith at the prompt, it will still
-;;  be expanded in the letter buffer because MH is case-insensitive.
-;;
-;;  When you press ", (mh-alias-minibuffer-confirm-address)" after an alias in
-;;  the minibuffer, the expansion for the previous mail alias appears briefly.
-;;  To inhibit this, customize the variable `mh-alias-flash-on-comma'.
-;;
-;;  The addresses and aliases entered in the minibuffer are added to the
-;;  message draft. To expand the aliases before they are added to the draft,
-;;  customize the variable `mh-alias-expand-aliases-flag'.
-;;
-;;  Completion is also performed on usernames extracted from the /etc/passwd
-;;  file. This can be a handy tool on a machine where you and co-workers
-;;  exchange messages, but should probably be disabled on a system with
-;;  thousands of users you don't know. This is done by customizing the
-;;  variable `mh-alias-local-users'. This variable also takes a string which
-;;  is executed to generate the password file. For example, you'd use "ypcat
-;;  passwd" for NIS.
-;;
-;;  Aliases are loaded the first time you send mail and get the "To:" prompt
-;;  and whenever a source of aliases changes. Sources of system aliases are
-;;  defined in the customization variable `mh-alias-system-aliases' and
-;;  include:
-;;
-;;    /etc/nmh/MailAliases
-;;    /usr/lib/mh/MailAliases
-;;    /etc/passwd
-;;
-;;  Sources of personal aliases are read from the files listed in your MH
-;;  profile component Aliasfile. Multiple files are separated by white space
-;;  and are relative to your mail directory.
-;;
-;;  Alias Insertions
-;;  ~~~~~~~~~~~~~~~~
-;;  There are commands to insert new aliases into your alias file(s) (defined
-;;  by the `Aliasfile' component in the .mh_profile file or by the variable
-;;  `mh-alias-insert-file').  In particular, there is a tool-bar icon to grab
-;;  an alias from the From line of the current message.

 ;; 1. MH-E Customization Groups
 ;;
-;;    These are the customization group definitions. These are organized in a
-;;    logical order. High-level, windows and toolbar, folder, message,
-;;    composing and hooks.
+;;    These are the customization group definitions. Every group has a
+;;    associated manual node. The ordering is alphabetical, except for the
+;;    groups mh-faces and mh-hooks which are last .
 ;;
 ;; 2. MH-E Customization
 ;;
-;;    Here are the actual customization variables. There is a sub-section for
-;;    each group in the MH-E Customization Groups section. Within each
-;;    section, variables are sorted alphabetically. The manual section
-;;    dictates which group a variable should be placed. New variables should
-;;    be placed in the section where they would most likely be defined.
+;;    These are the actual customization variables. There is a sub-section for
+;;    each group in the MH-E Customization Groups section, in the same order,
+;;    separated by page breaks. Within each section, variables are sorted
+;;    alphabetically.
 ;;
-;;    All hooks should be placed in the 'mh-hook group; in addition, add the
-;;    group in which the hook is defined in the manual (or, if it is new,
-;;    where it would be defined). These two actions insures that the hooks
-;;    appear last in each group.
+;; 3. Hooks
+;;
+;;    All hooks must be placed in the mh-hook group; in addition, add the
+;;    group associated with the manual node in which the hook is described.
+;;    Since the mh-hook group appears near the end of this file, the hooks
+;;    will appear at the end of these other groups.
+;;
+;; 4. Faces
+;;
+;;    Create a new face group if necessary; in this case, add the group
+;;    associated with the manual node in which the faces are described to the
+;;    faces' group definition. Since the face groups appear last, the face
+;;    groups will appear at the end of these other groups.

-If you wanted to incorporate that spool file into an MH folder called
-mh-e by pressing \"I m\" in folder-mode or by `M-x mh-inc-spool-mh-e',
-you would setup  `mh-inc-spool-list' with an entry:
-
- Spool file:  ~/mail/mh-e
- Folder:      mh-e
- Key binding: m
-
-Then, you could also install `xbuffy' and configure an extra mailbox like so:
-
-box ~/mail/mh-e
- title mh-e
- origMode
- polltime 10
- headertime 0
- command gnudoit -q '(mh-inc-spool-mh-e)'

-when clicking the xbuffy box with the middle mouse button."

   "*Non-nil means display face images in `mh-show-mode'.
-This flag controls the display of three kinds of faces.
-
-The first is the traditional X-Face header field. For GNU Emacs 21
-and above, the `uncompface' binary is required to be in the execute
-PATH for the display of X-Face images. It can be obtained from
-ftp://ftp.cs.indiana.edu/pub/faces/compface/compface.tar.Z.
-
-If the XEmacs you are using has internal support for X-Face images, then MH-E
-will display X-Face images in XEmacs \"out of the box\". Even if you don't have
-X-Face support compiled into your XEmacs, you can still see the X-Face images
-in MH-E with the aid of an external x-face package and `uncompface'. It is
-available from ftp://ftp.jpl.org/pub/elisp/. Download it, put its files in the
-`load-path' and MH-E will invoke it automatically.
-
-Second, MH-E supports the display of the Gnus-specific Face
-header field in GNU Emacs >= 21 and XEmacs. No external packages
-are required. More information about the Face header can be found
-at: http://quimby.gnus.org/circus/face/.
-
-Finally, MH-E can also display images from the X-Image-URL header field. The
-display of the images requires the `wget' program, available from
-http://www.gnu.org/software/wget/wget.html, to fetch the image and the
-`convert' program from the ImageMagick suite, available from
+
+MH-E can display the content of `Face:', `X-Face:', and `X-Image-URL:' header
+fields. If any of these fields occur in the header of your message, the
+sender's face will appear in the `From:' header field. If more than one of
+these fields appear, then the first field found in the order `Face:',
+`X-Face:', and `X-Image-URL:' will be used. Note that versions of GNU Emacs
+prior to 21.1 don't support the display of inline images, so face images are
+not displayed in these versions.
+
+The option `mh-show-use-xface-flag' is used to turn this feature on and off.
+This feature will be turned on by default if your system supports it.
+
+The first header field used, if present, is the Gnus-specific `Face:' field.
+The `Face:' field appeared in GNU Emacs 21 and XEmacs. For more information,
+see http://quimby.gnus.org/circus/face/. Next is the traditional `X-Face:'
+header field. The display of this field requires the `uncompface' program
+which can be obtained from
+ftp://ftp.cs.indiana.edu/pub/faces/compface/compface.tar.Z. Recent versions of
+XEmacs have internal support for `X-Face:' images. If your version of XEmacs
+does not, then you'll need both `uncompface' and the x-face package which is
+available at ftp://ftp.jpl.org/pub/elisp/.
+
+Finally, MH-E will display images referenced by the `X-Image-URL:' header
+field if neither the `Face:' nor the `X-Face:' fields are present. The display
+of the images requires `wget' (available from
+http://www.gnu.org/software/wget/wget.html), `fetch', or `curl' to fetch the
+image and the `convert' program from the ImageMagick suite, available from
 http://www.imagemagick.org/. Of the three header fields this is the most
 efficient in terms of network usage since the image doesn't need to be
-transmitted with every single mail. However its display needs the recipient to
-fetch a URL and this can be misused. So it is disabled by default. It can be
-enabled by customizing `mh-fetch-x-image-url'. Setting that to ask for
-confirmation before fetching seems like a good choice.

+Ranges
+======
+Many commands that operate on individual messages, such as `mh-forward' or
+`mh-refile-msg' take a RANGE argument. This argument can be used in several
+ways.
+
+If you provide the prefix argument (\\[universal-argument]) to these commands,
+then you will be prompted for the message range. This can be any legal MH
+range which can include messages, sequences, and the abbreviations (described
+in the mh(1) man page):
+
+<num1>-<num2>
+    Indicates all messages in the range <num1> to <num2>, inclusive. The range
+    must be nonempty.
+
+`<num>:N'
+`<num>:+N'
+`<num>:-N'
+    Up to N messages beginning with (or ending with) message num. Num may be
+    any of the pre-defined symbols: first, prev, cur, next or last.
+
+`first:N'
+`prev:N'
+`next:N'
+`last:N'
+    The first, previous, next or last messages, if they exist.
+
+`all'
+    All of the messages.
+
+For example, a range that shows all of these things is `1 2 3 5-10 last:5
+unseen'.
+
+If the option `transient-mark-mode' is set to t and you set a region in the
+MH-Folder buffer, then the MH-E command will perform the operation on all
+messages in that region.

-or more that were interesting, so I added a couple of points to be
-conservative and send any message with a score of 10 or more down the
-drain. You might want to use a score of 12 or 13 to be really conservative.
-I have found that this really decreases the amount of junk to review.
-
-Messages with a score of 5-9 are set aside for later review. The major
-weakness of rules-based filters is a plethora of false positives\; I catch one
-or two legitimate messages in here a week, so it is worthwhile to check.
-
-You might choose to do this analysis yourself to pick a good score for
-deleting spam sight unseen, or you might pick a score out of a hat, or you
-might choose to be very conservative and not delete any messages at all.

+Bogofilter is a Bayesian spam filtering program. Get it from your local
