Subject: [BUG] git commit --allow-empty-message -m '' fails
Message-ID: <CANuW5x0eKVAToG76rJr6+n-Fdg7E5c8mHb8NvnQUT2PBzxjjPQ@mail.gmail.com>

When passed the `--allow-empty-message` flag with no `-m`, `git
commit` will open the editor and allow you to exit with an empty
message, as expected.

However, when passed `-m ''` in addition to `--allow-empty-message`,
the commit fails. Example below:

    $ git commit -a --allow-empty-message -m ''
    error: switch `m' requires a value
    usage: git commit [<options>] [--] <pathspec>...
    ...

Shouldn't the `-m` switch know whether the `--allow-empty-message`
flag has been passed?

Thanks,
Josh
