Well, ok, but your initial report began:

   Make an RCS file writable with chmod +w without locking it.

If I instead use M-x toggle-read-only, make changes, and use C-x v v,
then I see the problem.

OK. It looks like that variable only affects RCS and SCCS?
In which case I am guessing that few people will care if the default
changes, so maybe we should just do that...
