Hello,
I am using Emacs 21.3.50 (CVS) on W2K (MSVC 6.0 build).
Scenerio:
- Open a file (as in my case:"~/bin/cinclude.pl")
- Do a Save As (to "~/bin/cinclude1_0.pl")
- A call to (vc-mcvs-registered "~/bin/cinclude1_0.pl") is made
- In the "while" loop, a call to (file-name-directory "~") [progressively
going to top dir]
- The above call returns "nil". IMHO, it should have called
"expand-file-name" internally inside "file-name-directory" or should
handle 'nil' and return 'nil' instead of throwing error.
A fix which solved my problem was: in loaddefs.el @23991, call
expand-file-name
(defun vc-mcvs-registered (file)
(let ((dir file))
(while (and (stringp dir)
(not (equal dir (setq dir (file-name-directory (expand-file-name dir)))))) ;; Modified here
(setq dir (if (file-directory-p
(expand-file-name "MCVS/CVS" dir))
t (directory-file-name dir))))
(if (eq dir t)
(progn
(load "vc-mcvs")
(vc-mcvs-registered file)))))

It's been fixed a while ago in vc-mcvs.el, but it seems nobody has
refreshed the loaddefs.el file since. The fix doesn't do the
expand-file-name but checks nil instead because I thought it was
neat that the search stops at ~ rather than going all the way to /.
Could someone commit a refreshed version of loaddefs.el ?
Mine has all kinds of unrelated stuff in it.
