I don't think there is a way. `--branches` can take a pattern (and there is always `--glob`), but we do not pass FNM_PATHNAME to fnmatch, so "*" will match across `/` boundaries.

You are stuck with:

  git log --branches=fc --not $(
    git for-each-ref --format='%(refname:short)' refs/heads |
    grep -v /
  )

which is at least robust due to the restrictions on refnames (i.e., no whitespace).

As an aside, I noticed that:

  git log --branches=does-not-exist

will see that we matched no refs and fall back to showing HEAD. That seems a bit surprising to me.
