(defadvice make-auto-save-file-name (after auto-save-remove-hash-mark ())
"return an autosave file name, replacing \"#\" with \"OCTOTHORPE\""
(setq ad-return-value
(replace-regexp-in-string "#" "OCTOTHORPE" ad-return-value)))
(ad-activate 'make-auto-save-file-name)
(defun auto-save-file-name-p (filename)
"Return non-nil if FILENAME can be yielded by `make-auto-save-file-name'.
FILENAME should lack slashes. You can redefine this for customization."
(string-match "^OCTOTHORPE.*OCTOTHORPE$" filename))
This advice will change "#" to "OCTOTHORPE" in the
auto-save-file-name, so you'll get save files like
/usr/users/muggerid/kingsx/OCTOTHORPEfoo.cOCTOTHORPE
That's much longer than you had, but doesn't contain the "#"
character, so you'll know right away if that was the culprit.
I've redefined auto-save-file-name-p (which you're allowed to do) so
that you can recover these auto-save-files.
