git-send-mail in sh

Finally giving up on git-send-email (I won't install the 6 perl-modules it requires and I don't know perl enough to remove the need for them), I hacked up a replacement in sh. It's more aptly named as well. ;)

It tries to be fairly newbie-friendly in what it accepts so that new developers on a project easily can submit patches upstream in the desired format.

This is just a draft. If anyone thinks it's a good idea then say so and I'll write the man-page and re-submit it as a proper patch.

It's better than the perl version because;
1. It doesn't have any requirements other than normal unix-commands and 
"mail" being in the path.
2. It can generate the patches on the fly, using git-format-patch.

It's worse than the perl version because;
1. It doesn't thread the patch-series (which I personally prefer anyway 
since it's easier to follow a thread on a particular patch that way).
2. The patches sent within the same second arrive in random order.

Sorry about the attachment btw. Thunderbird seems to wrap lines no matter what I tell it.

Thoughts? Comments?
