vc-merge should call (vc-find-backend-function backend 'merge-file) instead.
The change is trivial, but someone with any of the VCS listed above
installed should test it.

I could test it -- did you have any particular test scenario in mind?
Or are there test cases for this in vc-tests.el?

No, no tests.
A scenario would be some situation where using vc-merge makes sense.
I don't really remember how branches worked in SVN, much less CVS or RCS
to write this step by step.
Maybe testing is not even necessary: the change I'm proposing seems like
a no-brainer, it just removes the requirement for the 'merge' backend
methods to be defined (in per-file backends). No code uses them directly
anyway.

Yeah, me neither. :-/

I think you should just go ahead and push -- if this turns out to be a
problem in svn/cvs/rcs (which seems unlikely), somebody that uses those
will probably file a bug report in a few years.

Makes sense, pushed. Thanks.
