-;; File name completion does not do partial completion of directories
-;; on the path, e.g., "/u/b/f" will not complete to "/usr/bin/foo",
-;; but you can put *'s in the path to accomplish this: "/u*/b*/f".
-;; Stars are required for performance reasons.

;; In addition, this package includes a feature for accessing include
;; files. For example, `C-x C-f <sys/time.h> RET' reads the file

If `]' is in this string, it must come first.
If `^' is in this string, it must not come first.
If `-' is in this string, it must come first or right after `]'.

other file in that directory begin with that sequence of characters.

+Unless `PC-disable-includes' is non-nil, the `<...>' sequence is interpreted
