[TopGit RFC PATCH] tg mail: new command for mailing patches

Petr, since you've asked for help on this, here you are:

    $ tg mail [NAME]

a simple script to send one patch over email.


All it does is

    - call `tg patch` for actual patch preparation
    - extract email addresses from whom and where to send a mail
    - boils down to `git send-email`


It is self-hosted -- this mail was send by me with

    $ tg mail t/tg-mail


P.S. I'm not a bash guy, please do not beat me too much...

That shouldn't be needed. git send-email parses Cc: headers and the
To: comes from 'git config topgit.to', so you can re-use this.

Exactly for this reason I do not extract Cc. And git send-mail does not
extract From: -- it just asks to confirm From is GIT_COMMITTER_IDENT,
and there is no option to stop it doing so except providing explicit
--from <someone> (maybe i'm missing something?).

To: comes from 'git config topgit.to', so you can re-use this.

Yes, it comes directly to .topmsg when `tg create` is done, so I thought
the main source of information is the patch itself -- users may want to
edit that To: by hand or add another To: lines.

and what If a patch is already exported as a file, and I want to
send/resend it upstream right from that file?

We may want to look for topgit.to too though.

Ahh, my fault, I should take a break, sorry for the noise.

Yeah, my fault, I noticed this too, its just a template. better to
extract it from the patch.

No problem, your "noise" is welcome :)
