Fixes: debbugs:2138
It hasn't worked in a VC sense since 2008-05-02T07:12:59Z!esr@snark.thyrsus.com, though this was
not documented at the time (grr).
* lisp/vc/vc-hooks.el (vc-toggle-read-only): Make it an obsolete alias
for toggle-read-only. Note that this hasn't called vc-next-action
since 2008-05-02, though it wasn't documented at the time.
* lisp/files.el (toggle-read-only): Remove obsolete comment about
version control.
* doc/emacs/buffers.texi (Misc Buffer): Don't mention vc-toggle-read-only.
* lisp/cedet/ede.el (ede-maybe-checkout): Function deleted;
vc-toggle-read-only does not do version control now.
* lisp/cedet/ede/project-am.el (project-remove-file, project-add-file)
(project-new-target): Don't call ede-maybe-checkout.
* lisp/cedet/ede/util.el (ede-make-buffer-writable): Don't use
vc-toggle-read-only.
* lisp/vc/ediff-init.el (ediff-toggle-read-only-function): Use
toggle-read-only.
Tiny change; note that author said he placed it in the public domain.
(If this wasn't a tiny change, we would still need paperwork.)
* lisp/vc/ediff-init.el (ediff-use-faces, ediff-highlight-all-diffs):
Move ediff-defvar-local calls after defcustoms.
