+;;; Commentary:
+;;
+;;    Extensions to Dired.
+;;
+;;  This file extends functionalities provided by standard GNU Emacs
+;;  files `dired.el', `dired-aux.el', and `dired-x.el'.
+;;
+;;  Key bindings changed.  Menus redefined.  `diredp-mouse-3-menu'
+;;  popup menu added.  New commands.  Some commands enhanced.
+;;
+;;  All of the new functions, variables, and faces defined here have
+;;  the prefix `diredp-' (for Dired Plus) in their names.
+;;
+;;
+;;  Wraparound Navigation
+;;  ---------------------
+;;
+;;  In vanilla Dired, `dired-next-marked-file' (`M-}' or `* C-n') and
+;;  `dired-previous-marked-file' (`M-{' or `* C-p') wrap around when
+;;  you get to the end or the beginning of the Dired buffer.  Handy.
+;;
+;;  But the other navigation commands do not wrap around.  In `Dired+'
+;;  they do, provided option `diredp-wrap-around-flag' is non-nil,
+;;  which it is by default.  This means the following commands:
+;;
+;;    `diredp-next-line'     - `n', `C-n', `down', `SPC'
+;;    `diredp-previous-line' - `p', `C-p', `up'
+;;    `diredp-next-dirline'  - `>'
+;;    `diredp-prev-dirline'  - `<'
+;;    `diredp-next-subdir'   - `C-M-n'
+;;    `diredp-prev-subdir'   - `C-M-p'
+;;
+;;
+;;  Quick Viewing While Navigating
+;;  ------------------------------
+;;
+;;  You can use key `C-down' or `C-up' to navigate to the next or
+;;  previous file line, respectively, and at the same time show its
+;;  file in another window.  The focus remains on the Dired buffer.
+;;  A numeric prefix arg means move that many lines first.
+;;
+;;  Names of files and directories that match either of the options
+;;  `diredp-visit-ignore-extensions' or `diredp-visit-ignore-regexps'
+;;  are skipped.
+;;
+;;  You can use `e' to show the file of the current line.  If it is
+;;  already shown in the same frame, and if Dired is the only other
+;;  window there, then the file is hidden (its window is deleted).
+;;
+;;
+;;  Font-Lock Highlighting
+;;  ----------------------
+;;
+;;  If you want a maximum or minimum fontification for Dired mode,
+;;  then customize option `font-lock-maximum-decoration'.  If you want
+;;  a different fontification level for Dired than for other modes,
+;;  you can do this too by customizing
+;;  `font-lock-maximize-decoration'.
+;;
+;;  A few of the user options defined here have an effect on
+;;  font-locking, and this effect is established only when Dired+ is
+;;  loaded, which defines the font-lock keywords for Dired.  These
+;;  options include `diredp-compressed-extensions',
+;;  `diredp-ignore-compressed-flag', and `dired-omit-extensions'.
+;;  This means that if you change the value of such an option then you
+;;  will see the change only in a new Emacs session.
+;;
+;;  (You can see the effect in the same session if you use `C-M-x' on
+;;  the `defvar' sexp for `diredp-font-lock-keywords-1', and then you
+;;  toggle font-lock off and back on.)
+;;
+;;
+;;  Act on All Files
+;;  ----------------
+;;
+;;  Most of the commands (such as `C' and `M-g') that operate on the
+;;  marked files have the added feature here that multiple `C-u' use
+;;  not the files that are marked or the next or previous N files, but
+;;  *all* of the files in the Dired buffer.  Just what "all" files
+;;  means changes with the number of `C-u', as follows:
+;;
+;;    `C-u C-u'         - Use all files present, but no directories.
+;;    `C-u C-u C-u'     - Use all files and dirs except `.' and `..'.
+;;    `C-u C-u C-u C-u' - use all files and dirs, `.' and `..'.
+;;
+;;    (More than four `C-u' act the same as two.)
+;;
+;;  This feature can be particularly useful when you have a Dired
+;;  buffer with files chosen from multiple directories.
+;;
+;;  Note that in most cases this behavior is described only in the doc
+;;  string of function `dired-get-marked-files'.  It is generally
+;;  *not* described in the doc strings of the various commands,
+;;  because that would require redefining each command separately
+;;  here.  Instead, we redefine macro `dired-map-over-marks' and
+;;  function `dired-get-filename' in order to achieve this effect.
+;;
+;;  Commands such as `dired-do-load' for which it does not make sense
+;;  to act on directories generally treat more than two `C-u' the same
+;;  as two `C-u'.
+;;
+;;  Exceptions to the general behavior described here are called out
+;;  in the doc strings.  In particular, the behavior of a prefix arg
+;;  for `dired-do-query-replace-regexp' is different, so that you can
+;;  use it also to specify word-delimited replacement.
+;;
+;;
+;;  Act on Marked (or All) Files Here and Below
+;;  -------------------------------------------
+;;
+;;  The prefix argument behavior just described does not apply to the
+;;  `diredp-*-recursive' commands.  These commands act on the marked
+;;  files in the current Dired buffer or on all files in the directory
+;;  if none are marked.
+;;
+;;  But these commands also handle marked subdirectories recursively,
+;;  in the same way.  That is, they act also on the marked files in
+;;  any marked subdirectories, found recursively.  If such a
+;;  descendant directory is listed in a Dired buffer then its marked
+;;  files and subdirs are handled the same way.  If there is no Dired
+;;  buffer that lists a given marked subdirectory then all of its
+;;  files and subdirs are acted on.
+;;
+;;  For most such here-and-below commands, a prefix argument means
+;;  ignore all marks.  The commands then act on all files in the
+;;  current Dired buffer and all of its subdirectories, recursively.
+;;
+;;  But here-and-below commands that unmark or change marks act
+;;  differently for different kinds of prefix argument:
+;;
+;;  * A non-positive prefix arg means ignore subdir markings and act
+;;    instead on ALL subdirs.
+;;
+;;  * A non-negative prefix arg means do not change marks on subdirs
+;;    themselves.
+;;
+;;  For example, `M-+ U' removes all marks, including from marked
+;;  subdirs, recursively.  `C-- M-+ U' removes them from all files in
+;;  all subdirs (marked or not), recursively.  `C-9 M-+ U' removes all
+;;  marks, recursively, except the marks on subdirs themselves.  `C-0
+;;  M-+ U' acts like those two combined: it descends everywhere,
+;;  ignoring which subdirs are marked, but it does not remove marks
+;;  from subdirs themselves.
+;;
+;;  All of the `diredp-*-recursive' commands are on prefix key `M-+',
+;;  and all are available on submenu `Marked Here and Below' of the
+;;  `Multiple' menu-bar menu.  The commands that unmark and change
+;;  marks are also in submenu `Here and Below' of menu-bar menu
+;;  `Marks'.
+;;
+;;  If you use library `Icicles' then you have the following
+;;  additional commands/keys that act recursively on marked files.
+;;  They are in the `Icicles' submenu of menu `Multiple' > `Marked
+;;  Here and Below'.
+;;
+;;  * `M-+ M-s M-s' or `M-s M-s m' - Use Icicles search (and its
+;;                  on-demand replace) on the marked files.
+;;
+;;  * Save the names of the marked files:
+;;
+;;    `M-+ C-M->' - Save as a completion set, for use during
+;;                  completion (e.g. with `C-x C-f').
+;;
+;;    `M-+ C->'   - Add marked names to the names in the current saved
+;;                  completion set.
+;;
+;;    `M-+ C-}'   - Save persistently to an Icicles cache file, for
+;;                  use during completion in another session.
+;;
+;;    `icicle-dired-save-marked-to-fileset-recursive' - Like `M-+
+;;                  C-}', but save persistently to an Emacs fileset.
+;;
+;;    `M-+ C-M-}' - Save to a Lisp variable.
+;;
+;;
+;;  In the other direction, if you have a saved set of file names then
+;;  you can use `C-M-<' (`icicle-dired-chosen-files-other-window') in
+;;  Dired to open a Dired buffer for just those files.  So you can
+;;  mark some files and subdirs in a hierarchy of Dired buffers, use
+;;  `M-+ C-}' to save their names persistently, then later use `C-{'
+;;  to retrieve them, and `C-M-<' (in Dired) to open Dired on them.
+;;
+;;
+;;  Image Files
+;;  -----------
+;;
+;;  `Dired+' provides several enhancements regarding image files.
+;;  Most of these require standard library `image-dired.el'.  One of
+;;  them, command `diredp-do-display-images', which displays all of
+;;  the marked image files, requires standard library `image-file.el'.
+;;
+;;  `Dired+' loads these libraries automatically, if available, which
+;;  means an Emacs version that supports image display (Emacs 22 or
+;;  later).  (You must of course have installed whatever else your
+;;  Emacs version needs to display images.)
+;;
+;;  Besides command `diredp-do-display-images', see the commands whose
+;;  names have prefix `diredp-image-'.  And see options
+;;  `diredp-image-preview-in-tooltip' and
+;;  `diredp-auto-focus-frame-for-thumbnail-tooltip-flag'.
+;;
+;;
+;;  Inserted Subdirs, Multiple Dired Buffers, Files from Anywhere,...
+;;  -----------------------------------------------------------------
+;;
+;;  These three standard Dired features are worth pointing out.  The
+;;  third in particular is little known because (a) it is limited in
+;;  vanilla Dired and (b) you cannot use it interactively.
+;;
+;;   * You can pass a glob pattern with wildcards to `dired'
+;;     interactively, as the file name.
+;;
+;;   * You can insert multiple subdirectory listings into a single
+;;     Dired buffer using `i' on each subdir line.  Use `C-u i' to
+;;     specify `ls' switches.  Specifying switch `R' inserts the
+;;     inserted subdirectory's subdirs also, recursively.  You can
+;;     also use `i' to bounce between a subdirectory line and its
+;;     inserted-listing header line.  You can delete a subdir listing
+;;     using `C-u k' on its header line.  You can hide/show an
+;;     inserted subdir using `$'.  You can use `C-_' to undo any of
+;;     these operations.
+;;
+;;   * You can open a Dired buffer for an arbitrary set of files from
+;;     different directories.  You do this by invoking `dired'
+;;     non-interactively, passing it a cons of a Dired buffer name and
+;;     the file names.  Relative file names are interpreted relative
+;;     to the value of `default-directory'.  Use absolute file names
+;;     when appropriate.
+;;
+;;  `Dired+' makes these features more useful.
+;;
+;;  `$' is improved: It is a simple toggle - it does not move the
+;;  cursor forward.  `M-$' advances the cursor, in addition to
+;;  toggling like `$'.  `C-u $' does hide/show all (what `M-$' does in
+;;  vanilla Dired).
+;;
+;;  `i' is improved in these ways:
+;;
+;;   * Once a subdir has been inserted, `i' bounces between the subdir
+;;     listing and the subdir line in the parent listing.  If the
+;;     parent dir is hidden, then `i' from a subdir opens the parent
+;;     listing so it can move to the subdir line there (Emacs 24+).
+;;
+;;   * Vanilla Dired lets you create a Dired listing with files and
+;;     directories from arbitrary locations, but you cannot insert
+;;     (`i') such a directory if it is not in the same directory tree
+;;     as the `default-directory' used to create the Dired buffer.
+;;     `Dired+' removes this limitation; you can insert any non-root
+;;     directories (that is, not `/', `c:/', etc.).
+;;
+;;  `Dired+' lets you create Dired buffers that contain arbitrary
+;;  files and directories interactively, not just using Lisp.  Just
+;;  use a non-positive prefix arg (e.g., `C--') when invoking `dired'.
+;;
+;;  You are then prompted for the Dired buffer name (anything you
+;;  like, not necessarily a directory name) and the individual files
+;;  and directories that you want listed.
+;;
+;;  A non-negative prefix arg still prompts you for the `ls' switches
+;;  to use.  (So `C-0' does both: prompts for `ls' switches and for
+;;  the Dired buffer name and the files to list.)
+;;
+;;  `Dired+' adds commands for combining and augmenting Dired
+;;  listings:
+;;
+;;   * `diredp-add-to-dired-buffer', bound globally to `C-x D A', lets
+;;     you add arbitrary file and directory names to an existing Dired
+;;     buffer.
+;;
+;;   * `diredp-dired-union', bound globally to `C-x D U', lets you
+;;     take the union of multiple Dired listings, or convert an
+;;     ordinary Dired listing to an explicit list of absolute file
+;;     names.  With a non-positive prefix arg, you can add extra file
+;;     and directory names, just as for `diredp-add-to-dired-buffer'.
+;;
+;;  You can optionally add a header line to a Dired buffer using
+;;  toggle command `diredp-breadcrumbs-in-header-line-mode'.  (A
+;;  header line remains at the top of the window - no need to scroll
+;;  to see it.)  If you want to show the header line automatically in
+;;  all Dired buffers, you can do this:
+;;
+;;    (add-hook 'dired-before-readin-hook
+;;              'diredp-breadcrumbs-in-header-line-mode)
+;;
+;;  Some other libraries, such as `Bookmark+' and `Icicles', make it
+;;  easy to create or re-create Dired buffers that list specific files
+;;  and have a particular set of markings.  `Bookmark+' records Dired
+;;  buffers persistently, remembering `ls' switches, markings, subdir
+;;  insertions, and hidden subdirs.  If you use `Icicles' then `dired'
+;;  is a multi-command: you can open multiple Dired buffers with one
+;;  `dired' invocation.
+;;
+;;  Dired can help you manage projects.  You might have multiple Dired
+;;  buffers with quite specific contents.  You might have some
+;;  subdirectories inserted in the same Dired buffer, and you might
+;;  have separate Dired buffers for some subdirectories.  Sometimes it
+;;  is useful to have both for the same subdirectory.  And sometimes
+;;  it is useful to move from one presentation to the other.
+;;
+;;  This is one motivation for the `Dired+' `diredp-*-recursive'
+;;  commands, which act on the marked files in marked subdirectories,
+;;  recursively.  In one sense, these commands are an alternative to
+;;  using a single Dired buffer with inserted subdirectories.  They
+;;  let you use the same operations on the files in a set of Dired
+;;  directories, without inserting those directories into an ancestor
+;;  Dired buffer.
+;;
+;;  You can use command `diredp-dired-inserted-subdirs' to open a
+;;  separate Dired buffer for each of the subdirs that is inserted in
+;;  the current Dired buffer.  Markings and Dired switches are
+;;  preserved.
+;;
+;;  In the opposite direction, if you use `Icicles' then you can use
+;;  multi-command `icicle-dired-insert-as-subdir', which lets you
+;;  insert any number of directories you choose interactively into a
+;;  Dired ancestor directory listing.  If a directory you choose to
+;;  insert already has its own Dired buffer, then its markings and
+;;  switches are preserved for the new, subdirectory listing in the
+;;  ancestor Dired buffer.
+;;
+;;
+;;  Hide/Show Details
+;;  -----------------
+;;
+;;  Starting with Emacs 24.4, listing details are hidden by default.
+;;  Note that this is different from the vanilla Emacs behavior, which
+;;  is to show details by default.
+;;
+;;  Use `(' anytime to toggle this hiding.  You can use option
+;;  `diredp-hide-details-initially-flag' to change the default/initial
+;;  state.  See also option `diredp-hide-details-propagate-flag'.
+;;
+;;  NOTE: If you do not want to hide details initially then you must
+;;        either (1) change `diredp-hide-details-initially-flag' using
+;;        Customize (recommended) or (2) set it to `nil' (e.g., using
+;;        `setq') *BEFORE* loading `dired+.el'.
+;;
+;;  If you have an Emacs version older than 24.4, you can use library
+;;  `dired-details+.el' (plus `dired-details.el') to get similar
+;;  behavior.
+;;
+;;
+;;  Mode-Line
+;;  ---------
+;;
+;;  The number of files and dirs that are marked with `*', and the
+;;  number that are flagged for deletion (marked `D') are indicated in
+;;  the mode-line.  When the cursor is on such a line the indication
+;;  tells you how many more there are.  For example, if the cursor is
+;;  on the line of the third file that is marked `*', and there are
+;;  seven of them total, then the mode-line shows `3/7*'.
+;;
+;;  The mode-line also indicates, for the current listing (which could
+;;  be a subdir listing), how many files and dirs are listed.  If the
+;;  cursor is on the 27th file in a listing of 78 files then the
+;;  mode-line shows 27/78.
+;;
+;;  For counting files and dirs in a listing, option
+;;  `diredp-count-.-and-..-flag' controls whether to count the lines
+;;  for `.' and `..'.  By default it is nil, meaning they are not
+;;  counted.
+;;
+;;
+;;  If You Use Dired+ in Terminal Mode
+;;  ----------------------------------
+;;
+;;  By default, Dired+ binds some keys that can be problematic in some
+;;  terminals when you use Emacs in terminal mode (i.e., `emacs -nw').
+;;  This is controlled by option
+;;  `diredp-bind-problematic-terminal-keys'.
+;;
+;;  In particular, keys that use modifiers Meta and Shift together can
+;;  be problematic.  If you use Dired+ in text-only terminal, and you
+;;  find that your terminal does not support such keys, then you might
+;;  want to customize the option to set the value to `nil', and then
+;;  bind the commands to some other keys, which your terminal
+;;  supports.
+;;
+;;  The problematic keys used by Dired+ include these:
+;;
+;;    `M-M'   (aka `M-S-m')   - `diredp-chmod-this-file'
+;;    `M-O'   (aka `M-S-o')   - `diredp-chown-this-file'
+;;    `M-T'   (aka `M-S-t')   - `diredp-touch-this-file'
+;;    `C-M-B' (aka `C-M-S-b') - `diredp-do-bookmark-in-bookmark-file'
+;;    `C-M-G' (aka `C-M-S-g') - `diredp-chgrp-this-file'
+;;    `C-M-R' (aka `C-M-S-r') - `diredp-toggle-find-file-reuse-dir'
+;;    `C-M-T' (aka `C-M-S-t') - `dired-do-touch'
+;;    `M-+ M-B'   (aka `M-+ M-S-b') -
+;;        `diredp-do-bookmark-dirs-recursive'
+;;    `M-+ C-M-B' (aka `M-+ C-M-S-b') -
+;;        `diredp-do-bookmark-in-bookmark-file-recursive'
+;;    `M-+ C-M-T' (aka `M-+ C-M-S-t') - `diredp-do-touch-recursive'
+;;
+;;  (See also `(info "(org) TTY keys")' for more information about

+  "Interactively, a prefix argument changes the behavior as follows:
+
+* If >= 0, you are first prompted for the `ls' switches to use.
+
+* If <= 0, you are prompted first for the name of the Dired  buffer.
+  Then you are prompted repeatedly for the names of the directories
+  or files to list in the buffer.  You can use file-name wildcards
+  (i.e., `*' for globbing), to include the matching files and
+  directories.  Use `C-g' to end.
+
+  In other words, instead of listing a single directory, the Dired
+  buffer can list any number of directories and file names, which can
+  even belong to different directory trees.
+
+The rest of this description applies only if you use Icicles.
+
+In Icicle mode this is a multi-command: You can cycle among file-name
+completion candidates and act individually on those that name
+directories.  The action is to open Dired for the directory.  While
+cycling, these keys are active:
+
+\\<minibuffer-local-completion-map>\
+`C-mouse-2', `C-return' - Act on current completion candidate only
+`C-down', `C-wheel-down' - Move to next completion candidate and act
+`C-up', `C-wheel-up' - Move to previous completion candidate and act
+`C-next'  - Move to next apropos-completion candidate and act
+`C-prior' - Move to previous apropos-completion candidate and act
+`C-end'   - Move to next prefix-completion candidate and act
+`C-home'  - Move to previous prefix-completion candidate and act
+`\\[icicle-all-candidates-action]'     - Act on *all* candidates, successively (careful!)
+`\\[icicle-all-candidates-list-alt-action]'     - Open Dired on all candidates
+
+When candidate action and cycling are combined (e.g. `C-next'), user
+option `icicle-act-before-cycle-flag' determines which occurs first.
+
+With prefix `C-M-' instead of `C-', the same keys (`C-M-mouse-2',
+`C-M-RET', `C-M-down', and so on) provide help about candidates.
+
+Use `mouse-2', `RET', or `S-RET' to finally choose a candidate, or
+`C-g' to quit.
+
+These keys are also bound in the minibuffer during completion (`*'
+means the key requires library `Bookmark+'):
+
+   S-delete    - Delete candidate file or (empty) dir
+   C-c +       - Create a new directory
+   C-backspace - Go up one directory level
+ * C-x C-t *   - Narrow to files with all of the tags you specify
+ * C-x C-t +   - Narrow to files with some of the tags you specify
+ * C-x C-t % * - Narrow to files with all tags matching a regexp
+ * C-x C-t % + - Narrow to files with some tags  matching a regexp
+ * C-x a +     - Add tags to the current-candidate file
+ * C-x a -     - Remove tags from the current-candidate file

+With a non-negative prefix arg, you are prompted for `ls' switches.
+With a non-positive prefix arg, you are prompted for file and dir
+names to add to the listing - see below.
+
+You are prompted for the name of the Dired union buffer.  Completion
+against names of existing Dired buffers is available, but you can
+enter any other name to create a new Dired buffer of that name.
+
+If the union buffer name you choose names an existing Dired buffer,
+then what happens depends on whether that buffer is an ordinary Dired
+directory listing or a list of arbitrary file names.  That is, it
+depends on whether `dired-directory' is a directory name or a cons of
+a Dired buffer name plus file names.
+
+* If the buffer is an ordinary Dired listing, then it is converted to
+  an explicit list of absolute file names, just as if these had been
+  chosen individually.  The existing buffer and window are replaced by
+  new ones that show the explicit listing.  (This replacement is
+  necessary because the list of files contained in an ordinary Dired
+  listing cannot be modified.)
+
+* If the buffer lists arbitrary file names explicitly, then it is
+  updated to include also the files from any Dired buffers and any
+  additional files that you specify.
+
+If the union buffer name you choose does not name an existing Dired
+buffer, then its `default-directory' is the same as the
+`default-directory' before invoking the command.
+
+If you use a non-positive prefix arg, then you can next choose
+additional file and directory names to add to the listing.  Use `C-g'
+when done choosing them.
+
+Any directory names you choose this way are included as single entries
+in the listing - the directory contents are not included (these
+directories are not unioned).  To instead include the contents of a
+directory chosen this way, use a glob pattern: `/*' after the
+directory name.
+
+You are then prompted for the Dired buffers to union.  Use `C-g' when
+done choosing them.  These Dired listings to union are included in the
+order that you chose them, and each entry is listed only once in the
+new Dired buffer.
+
+The new Dired listing respects the markings, subdirectory insertions,
+and hidden subdirectories of the selected Dired listings.  However, in
+case of conflict between marked or unmarked status for the same entry,
+the entry is marked.  Similarly, in case of conflict over an included
+subdirectory between it being hidden or shown, it is hidden, but its
+contained files are also listed.

+
+Whether to mark or unmark, and what form of file name to match, are
+governed by the prefix argument.  For this, a plain (`C-u') or a
+double-plain (`C-u C-u') prefix arg is considered only as such - it is
+not considered numerically.
+
+Whether to mark or unmark:
+
+ - No prefix arg, a positive arg, or a negative arg means mark.
+
+ - Plain (`C-u'), double-plain (`C-u C-u'), or zero (e.g. `M-0' means
+   unmark.
+
+The form of a file name used for matching:
+
+ - No prefix arg (to mark) or a plain prefix arg (`C-u', to unmark)
+   means use the relative file name (no directory part).
+
+ - A negative arg (e.g. `M--', to mark) or a zero arg (e.g. `M-0', to
+   unmark) means use the absolute file name, that is, including all
+   directory components.
+
+ - A positive arg (e.g. `M-+', to mark) or a double plain arg (`C-u
+   C-u', to unmark) means construct the name relative to
+   `default-directory'.  For an entry in an inserted subdir listing,
+   this means prefix the relative file name (no directory part) with
+   the subdir name relative to `default-directory'.
+
+Note that the default matching behavior of this command is different
+for Dired+ than it is for vanilla Emacs.  Using a positive prefix arg
+or a double plain prefix arg (`C-u C-u') gives you the same behavior
+as vanilla Emacs (marking or unmarking, respectively): matching
+against names that are relative to the `default-directory'.
+
+What Dired+ offers in addition is the possibility to match against
+names that are relative (have no directory part - no prefix arg or
+`C-u' to mark and unmark, respectively) or absolute (`M--' or `M-0',
+respectively).  The default behavior uses relative names because this
+is likely to be the more common use case.  But matching against
+absolute names gives you more flexibility.
+
+REGEXP is an Emacs regexp, not a shell wildcard.  Thus, use `\\.o$'
+for object files--just `.o' might mark more than you might expect.
+
+REGEXP is added to `regexp-search-ring', for regexp search.
+
+Non-interactively:
+ MARKER-CHAR is the marker character - used for `dired-marker-char'.
+ LOCALP is passed to `dired-get-filename'.  It determines the form of

+     First, Dired just the source files: `dired *.el'.
+     Then, use \\[dired-mark-sexp] with this sexp:
+          (not (file-exists-p (concat name \"c\")))
+
+There's an ambiguity when a single integer not followed by a unit
+prefix precedes the file mode: It is then parsed as inode number
+and not as block size (this always works for GNU coreutils ls).
+
+Another limitation is that the uid field is needed for the
+function to work correctly.  In particular, the field is not
+present for some values of `ls-lisp-emulation'.
+
+This function operates only on the Dired buffer content.  It does not
+refer at all to the underlying file system.  Contrast this with
+`find-dired', which might be preferable for the task at hand."
+  ;; Using `sym' = "", instead of nil, for non-linked files avoids the trap of
+  ;; (string-match "foo" sym) into which a user would soon fall.
+  ;; Use `equal' instead of `=' in the example, as it works on integers and strings.
