That was not my intention. When used in a repository, it behaves
exactly the same as before, including @{-1} resolution part. And by
using strbuf_check_branch_ref(), it has always been checking the
validity of a potential branch name, even though it wasn't
advertised as such. The documentation needs to be updated, I would
think.
When used outside a repository, @{-1} would not have worked anyway,
and @{-1} continues not to work, but the part that checks the
validity should continue to work.
At least that is what I wanted to happen in the patch.
