Using the current pretest 24.0.94, I noticed that when vc-merge prompts me
for the branch or revision to merge, the message misses a space after the
filename, e.g.

    Merge /home/leinen/cl/fluxoscope/snmp-get-info.lispfrom branch or
revision (default news on current branch):

Here's the one-character fix.  Hopefully Gmail doesn't break the patch,
otherwise I can resend it as an attachment.
