OK, I'll try to make a few final modifications and push them.

I am not sure whether I understand.  The problem was specifically with
lisp version of `beginning-of-defun'.  With other modes, there is a bit of
a mess: some modes set `beginning-of-defun-function' (e.g. js-mode and
js2-mode), some rebind C-M-a to their beginning-of-defun (e.g. c-mode).
Now, other modes (again, I used c-mode and js2-mode for reference) do
various things when arg=0 for beginning-of-defun - e.g. c-mode claims to
go back to the current defun's header, js2-mode just pretends that arg
is 1 etc.

Unifying that (1) might not be the best idea and (2) would require quite
a lot of work for all Emacs built-in modes.

I could try to do that, but this would take a bit.  Also, I do not know
many of the languages involved, and I'd prefer not to touch their
modes.

No problem,
