cherry-pick: add --allow-empty-message option

Browse Source 
Scripts such as "git rebase -i" cannot currently cherry-pick commits
which have an empty commit message, as git cherry-pick calls git
commit without the --allow-empty-message option.

Add an --allow-empty-message option to git cherry-pick which is passed
through to git commit, so this behaviour can be overridden.

By default, cherry-picking a commit with an empty message will fail.
This option overrides that behaviour, allowing commits with empty
messages to be cherry picked.
--keep-redundant-commits::
If a commit being cherry picked duplicates a commit already in the
current history, it will become empty. By default these
