Add option to git-commit to allow empty log messages

Change git-commit(1) to accept the --allow-empty-message option
to allow a commit with an empty message.  This is analogous to the
existing --allow-empty option which allows a commit that records
no changes.  As these are mainly for interoperating with foreign SCM
systems, and are not meant for normal use, ensure that "git commit -h"
does not talk about them.
