Subject: git-mv: Allow -h without repo & fix error message
X-Git-Tag: v1.2.4~2
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=5e6f85f6c1d988d125dfcba16bb43a9a65f9eab3;p=git.git

git-mv: Allow -h without repo & fix error message

This fixes "git-mv -h" to output the usage without the need
to be in a git repository.
Additionally:
- fix confusing error message when only one arg was given
- fix typo in error message
