Not necessarily. :)
I noticed this today, and bisected it to this patch:
$ git.v1.7.7 show config
fatal: ambiguous argument 'config': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
$ git.mh.check-ref-format-3 show config
warning: reference in .git/config is formatted incorrectly
warning: reference in .git/config is formatted incorrectly
fatal: ambiguous argument 'config': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
which is arguably not a big deal, as we eventually report failure
anyway. But it's even worse with:
$ git branch config v1.7.7
$ git show --oneline config
warning: reference in .git/config is formatted incorrectly
703f05a Git 1.7.7
As you probably guessed, this is due to the ref resolution rules first
looking directly in .git for refs, which catches things like "HEAD" and
fully-qualified refs like "refs/heads/foo".
Which means we have been considering ".git/config" as a possible ref for
a long time, which is arguably wrong. Your patch only makes it more
obvious that this is the case.
I wonder if the right solution is for us to be more picky about what can
be found in $GIT_DIR. Maybe matching all-uppercase, or starting with
"refs/", which I think would match existing convention?
