2005-03-25  Katsumi Yamaoka  <yamaoka@jpl.org>

   * lisp/gnus/message.el (message-resend): Bind rfc2047-encode-encoded-words.

   * lisp/gnus/mm-util.el (mm-replace-in-string): New function.
   (mm-xemacs-find-mime-charset-1): Ignore errors while loading
   latin-unity, which cannot be used with XEmacs 21.1.

   * lisp/gnus/rfc2047.el (rfc2047-encode-function-alist): Rename from
   rfc2047-encoding-function-alist in order to avoid conflicting with
   the old version.
   (rfc2047-encode-message-header): Remove useless goto-char.
   (rfc2047-encodable-p): Don't move point.
   (rfc2047-syntax-table): Treat `(' and `)' as is.
   (rfc2047-encode-region): Concatenate words containing non-ASCII
   characters in structured fields; don't encode space-delimited
   ASCII words even in unstructured fields; don't break words at
   char-category boundaries; encode encoded words in structured
   fields; treat text within parentheses as special; show the
   original text when error has occurred; move point to the end of
   the region after encoding, suggested by IRIE Tetsuya
   <irie@t.email.ne.jp>; treat backslash-quoted characters as
   non-special; check carefully whether to encode special characters;
   fix some kind of misconfigured headers; signal a real error if
   debug-on-quit or debug-on-error is non-nil; don't infloop,
   suggested by Hiroshi Fujishima <pooh@nature.tsukuba.ac.jp>; assume
   the close parenthesis may be included in the encoded word; encode
   bogus delimiters.
   (rfc2047-encode-string): Use mm-with-multibyte-buffer.
   (rfc2047-encode-max-chars): New variable.
   (rfc2047-encode-1): New function.
   (rfc2047-encode): Use it; encode text so that it occupies the
   maximum width within 76-column; work correctly on Q encoding for
   iso-2022-* charsets; fold the line before encoding; don't append a
   space if the encoded word includes close parenthesis.
   (rfc2047-fold-region): Use existing whitespace for LWSP; make it
   sure not to break a line just after the header name.
   (rfc2047-b-encode-region): Remove.
   (rfc2047-b-encode-string): New function.
   (rfc2047-q-encode-region): Remove.
   (rfc2047-q-encode-string): New function.
   (rfc2047-encode-parameter): New function.
   (rfc2047-encoded-word-regexp): Don't use shy group.
   (rfc2047-decode-region): Follow rfc2047-encoded-word-regexp change.
   (rfc2047-parse-and-decode): Ditto.
   (rfc2047-decode): Treat the ascii coding-system as raw-text by
   default.

2005-03-25  Lars Magne Ingebrigtsen  <larsi@gnus.org>

   * lisp/gnus/rfc2047.el (rfc2047-encode-encoded-words): New variable.
   (rfc2047-field-value): Strip props.
   (rfc2047-encode-message-header): Disabled header folding -- not
   all headers can be folded, and this should be done by the message
   composition mode.  Probably.  I think.
   (rfc2047-encodable-p): Say that =? needs encoding.
   (rfc2047-encode-region): Encode =? strings.

2005-03-25  Jesper Harder  <harder@ifa.au.dk>

   * lisp/gnus/rfc2047.el (rfc2047-encoded-word-regexp): Support RFC 2231
   language tags; remove unnecessary '+'.  Reported by Stefan Wiens
   <s.wi@gmx.net>.
   (rfc2047-decode-string): Don't cons a string unnecessarily.
   (rfc2047-parse-and-decode, rfc2047-decode): Use a character for
   the encoding to avoid consing a string.
   (rfc2047-decode): Use mm-subst-char-in-string instead of
   mm-replace-chars-in-string.

2005-03-25  TSUCHIYA Masatoshi  <tsuchiya@namazu.org>

   * lisp/gnus/rfc2047.el (rfc2047-encode): Use uppercase letters to specify
   encodings of MIME-encoded words, in order to improve
   interoperability with several broken MUAs.

2005-03-21  Reiner Steib  <Reiner.Steib@gmx.de>

   * lisp/gnus/gnus-srvr.el (gnus-browse-select-group): Add NUMBER argument and
   pass it to `gnus-browse-read-group'.
