generating format-patch options from an e-mail

Hi all

I've been very frustrated by the process to setup a commandline for git format-patch, to include everyone in the cc list and reply to the right message-id.

In my frustration I created a perl script to generate the options from a saved e-mail, I realise that it may be non-general and perhaps it could be written better using a module which understands e-mails, but well, it worked for me ;-)

Anyway, I could imagine this as optional flag of git format-patch, so you could say:
$ git format-patch -s --in-reply-to-email <mboxfile> a7fe7de8

But I'll save that as an exercise for the reader (or the future)

Cheers

Simon

PS, now with the script
