vc-cvs-stay-local vs vc-stay-local

[Jason Rumney]

While trying to help a user who was disturbed by the CVS backup files
that Emacs now creates, I came across vc-stay-local. After advising
him to set that to nil, it did not appear to do anything. Apparently
he needs to set vc-cvs-stay-local instead, but there is no mention of
that in the doc string for vc-stay-local, in fact both doc strings are
exactly the same. After starting emacs -Q, vc-stay-local is listed as
a completion for C-h v vc- but vc-cvs-stay-local is not.

Do we need both these variables? If so, the way they interact with
each other is not at all clear, so the doc strings need some work.

Thanks for the hint.  vc-stay-local is supposed to be a global setting,
and vc-cvs-stay-local, if defined, is supposed to override it for CVS
only.  The problem is that currently both variables are defined via
defcustom, and so vc-cvs-stay-local always overrides whatever you
specify in vc-stay-local.

This needs to be fixed, you are right.  I'm thinking about a solution.
