Re: merging initial part of a branch?

That's the only reference I can find to the "tag <tag>" notation, and
it's a bit unhelpful as written.  (What backward compatibility?)

How about the following?--b.

Makes sense.  Thanks.

Backward compatibility is that it was only either "<branch>" or
"tag <tag>".  When heads/branch or tags/tag came later,
supporting the separate word form "tag <tag>" was a bit
cumbersome but was done for b/c.
