Re: [PATCH] branch: make --show-current use already resolved HEAD

I did something that resulted in the mailing list not being cc'd.
Apologies to Junio and Daniels for the double send. :(

Over at #git, commit messages are sometimes consulted to disambiguate or
clarify certain details. Often the documentation is correct but people
dispute over interpretations.

If someone came asking if `git branch` is parsable, I would advise
against and direct them to the plumbing or format alternative. But if
someone came over with a link to this commit asking the same question,
I suspect the answer would be: it's probably safe to parse the output of
this specific option because the commit says so. Thanks for clarifying
this is wrong.

I was not sure if these 3 lines were global intentionally or if it was
just an artifact from the past. Since it looks like the latter, I'll
make them local.
