I noticed this because it got a warning. It seems rather a kludge.
Is there any more general feature that could be used here?
(defun ff-which-function-are-we-in ()
"Return the name of the function whose definition/declaration point is in.
Also remember that name in `ff-function-name'."
(setq ff-function-name nil)
(save-excursion
(if (re-search-backward ada-procedure-start-regexp nil t)
(setq ff-function-name (buffer-substring (match-beginning 0)
(match-end 0)))
; we didn't find a procedure start, perhaps there is a package
(if (re-search-backward ada-package-start-regexp nil t)
(setq ff-function-name (buffer-substring (match-beginning 0)
(match-end 0)))
))))

What exactly is the problem here? It's an example in find-file.el to
illustrate an extension mechanism it supports. Is it just that the
function returns a value as well as storing it by side-effect?
