toggle-read-only / vc stupidity

toggle-read-only / vc stupidity

[Miles Bader]

toggle-read-only sometimes gives a message like:

   File is under version-control; use C-x v v to check in/out

1) Such a message may make sense with RCS, but it's just confusing
   with any modern source-control system (even CVS!).  [I'm using arch]

2) I only seem to get the message for files that _aren't_ under
   version-control (but are in a version-controlled directory)!

   [I suppose maybe what's happening is that it's backend-specific for
   registered files, but uses some generic code for non-registered
   files??]

IIRC This should only happen when a file under VC is read-only and you make
the buffer read-write with C-x C-q.  The warning is present to remind people
that C-x C-q doesn't do vc-toggle-read-only any more.

Actually I think it makes sense (or not) for any backend since it's just
linked to the change from vc-toggle-read-only to vc-toggle-read-only.

That's a bug.

       File is under version-control; use C-x v v to check in/out

It is just a helpful message -- it doesn't change what
toggle-read-only actually does.

The original reason for it was that formerly C-x C-q actually did a
check-in or check-out.  That was natural with RCS.  When we changed
C-x C-q not to do VC operations, we wanted to warn users who still
expected it to do so.

That change was released in Emacs 22, so it is too soon
to get rid of the warning.
