-;;; Commentary:
-
-;; Extended completion for the Emacs minibuffer.
-;;
-;; The basic idea is that the command name or other completable text is
-;; divided into words and each word is completed separately, so that
-;; "M-x p-b" expands to "M-x print-buffer".  If the entry is ambiguous
-;; each word is completed as much as possible and then the cursor is
-;; left at the first position where typing another letter will resolve
-;; the ambiguity.
-;;
-;; Word separators for this purpose are hyphen, space, and period.
-;; These would most likely occur in command names, Info menu items,
-;; and file names, respectively.  But all word separators are treated
-;; alike at all times.
-;;
-;; This completion package replaces the old-style completer's key
-;; bindings for TAB, SPC, RET, and `?'.  The old completer is still
-;; available on the Meta versions of those keys.  If you set
-;; PC-meta-flag to nil, the old completion keys will be left alone
-;; and the partial completer will use the Meta versions of the keys.
-
-
-;; Usage:  M-x partial-completion-mode.  During completable minibuffer entry,
-;;
-;;     TAB    means to do a partial completion;
-;;     SPC    means to do a partial complete-word;
-;;     RET    means to do a partial complete-and-exit;
-;;     ?      means to do a partial completion-help.
-;;
-;; If you set PC-meta-flag to nil, then TAB, SPC, RET, and ? perform
-;; original Emacs completions, and M-TAB etc. do partial completion.
-;; To do this, put the command,
-;;
-;;       (setq PC-meta-flag nil)
-;;
-;; in your .emacs file.  To load partial completion automatically, put
-;;
-;;       (partial-completion-mode t)
-;;
-;; in your .emacs file, too.  Things will be faster if you byte-compile
-;; this file when you install it.
-;;
-;; As an extra feature, in cases where RET would not normally
-;; complete (such as `C-x b'), the M-RET key will always do a partial
-;; complete-and-exit.  Thus `C-x b f.c RET' will select or create a
-;; buffer called "f.c", but `C-x b f.c M-RET' will select the existing
-;; buffer whose name matches that pattern (perhaps "filing.c").
-;; (PC-meta-flag does not affect this behavior; M-RET used to be
-;; undefined in this situation.)
-;;
-;; The regular M-TAB (lisp-complete-symbol) command also supports
-;; partial completion in this package.
-
-;; In addition, this package includes a feature for accessing include
-;; files.  For example, `C-x C-f <sys/time.h> RET' reads the file
-;; /usr/include/sys/time.h.  The variable PC-include-file-path is a
-;; list of directories in which to search for include files.  Completion
-;; is supported in include file names.

-With prefix ARG, turn Partial Completion mode on if ARG is positive.
-
-When Partial Completion mode is enabled, TAB (or M-TAB if `PC-meta-flag' is
-nil) is enhanced so that if some string is divided into words and each word is
-delimited by a character in `PC-word-delimiters', partial words are completed
-as much as possible and `*' characters are treated likewise in file names.
-
-For example, M-x p-c-m expands to M-x partial-completion-mode since no other
-command begins with that sequence of characters, and
-\\[find-file] f_b.c TAB might complete to foo_bar.c if that file existed and no
-other file in that directory begins with that sequence of characters.
-
-Unless `PC-disable-includes' is non-nil, the `<...>' sequence is interpreted
-specially in \\[find-file].  For example,
-\\[find-file] <sys/time.h> RET finds the file `/usr/include/sys/time.h'.
-See also the variable `PC-include-file-path'.
-
-Partial Completion mode extends the meaning of `completion-auto-help' (which
-see), so that if it is neither nil nor t, Emacs shows the `*Completions*'
-buffer only on the second attempt to complete.  That is, if TAB finds nothing
-to complete, the first TAB just says \"Next char not unique\" and the
-second TAB brings up the `*Completions*' buffer."

-    ;; The first call to PC-l-c-s expands this to "(ne-f", and moves
-    ;; point to the hyphen [1]. If one calls PC-l-c-s immediately after,
-    ;; then without the last-command check, one is offered all
-    ;; completions of "(ne", which is presumably not what one wants.
-    ;;
-    ;; This is arguably (at least, it seems to be the existing intended
-    ;; behavior) what one _does_ want if point has been explicitly
-    ;; positioned on the hyphen. Note that if PC-do-completion (qv) binds
-    ;; completion-base-size to nil, then completion does not replace the
-    ;; correct amount of text in such cases.
-    ;;
-    ;; Neither of these problems occur when using PC for filenames in the
-    ;; minibuffer, because in that case PC-do-completion is called without
-    ;; an explicit value for END, and so uses (point-max). This is fine for
-    ;; a filename, because the end of the filename must be at the end of
-    ;; the minibuffer. The same is not true for lisp symbols.
-    ;;
-    ;; [1] An alternate fix would be to not move point to the hyphen
-    ;; in such cases, but that would make the behavior different from
-    ;; that for filenames. It seems PC moves point to the site of the
-    ;; first difference between the possible completions.
