[PATCH v2 1/3] send-email: allow send-email to run outside a repo

From: Jay Soffian <jaysoffian@gmail.com>

Message-ID: <1234672335-54321-2-git-send-email-jaysoffian@gmail.com>
In-Reply-To: <1234672335-54321-1-git-send-email-jaysoffian@gmail.com>

send-email is supposed to be able to run from outside a repo. This ability was broken by commits caf0c3d6 (make the message file name more specific) and 5df9fcf6 (interpret unknown files as revision lists).

This commit provides a fix for both.

Junio,

I think you have this one applied already, but I don't currently in next nor pu, so I rebased it on next. I also put it first in the series per your request.
