Can't start new branch in VC with RCS

Can't start new branch in VC with RCS

[allan gottlieb]

I have a single file class-notes.html (with RCS/class-notes.html,v).
I am using rcs in default (locking) mode

The head revision is 8.6.  I am the only user and the head revision is
locked by me.  C-x v = shows the one simple change I made since 8.6.1
and the file has been saved.

I want to start branch 8.6.1.  The manual suggests C-u C-x v v.

C-u x v v asks for a new backend.  I do not want to change backends.
If I type RCS, it correctly reports that RCS is the current backend and
exits.  If I try 8.6.1, it correctly reports that there is no match (it
is looking for a backend).

Is this supposed to be possible under VC for RCS?  I presumably could
achieve my goal using rcs directly from the command line.

Thanks in advance.

Hi Allan,

For the record, I was unable to coerce, cajole, or otherwise
convince VC to create new branches in RCS.  I had to use the
command line.  It wasn't hard to do, but it would have been nice
if VC had the capability.  Perhaps it does and we just haven't see
it?

What version of Emacs is that?

The upcoming 25.1 will fix this.
