Documentation
Alist of (KEY . FUNCTION) pairs parsed by ffap-file-at-point.
If string NAME at point (maybe "") is not a file or URL, these pairs
specify actions to try creating such a string. A pair matches if either
KEY is a symbol, and it equals major-mode, or
KEY is a string, it should match NAME as a regexp.
On a match, (FUNCTION NAME) is called and should return a file, an
URL, or nil. If nil, search the alist for further matches.
While calling FUNCTION, the match data is set according to KEY if KEY
is a string, so that FUNCTION can use match-string and friends
to extract substrings.

;; Defined in /usr/src/emacs/lisp/ffap.el.gz

;; These search actions depend on the major-mode or regexps matching
;; the current name. The little functions and their variables are
;; deferred to the next section, at some loss of "code locality".
