Add --recursive flag to git bash completion script.

This is a patch to add a much needed option to the bash completion script. I'm not subscribed to this list, so please include me in your reply if you'd like me to see your response.

Thanks,
James

Subject: [PATCH] Add --recursive flag to git bash completion script.

This flag was missing from the list, and I use it quite often :)

Please read the guide on how to submit patches [1].

Although the change is trivial, some immediate problems I see are:

* The patch is attached rather than being inlined.
* The fix should also be made for the other shells (zsh and tcsh)
* The commit message contains an unnecessary smiley, personal digression, and a period in the first line.
* The change or the problem it is solving is not clearly described. I think it would be better if you write something like this in the first line:

"completion: add --recursive flag to git clone"

And for good measure, add another sentence below explaining why this should be available for completion.

Do a git log --grep completion to see how others have formulated changes in the same place in the past. You want to be consistent with them.
