[PATCH] VIM: Better reply handling with multiple emails

[Ian Main <imain@stemwinder.org>]

This patch fixes reply handling when using multiple emails.  This adds a
config check for other_email and uses that information when formulating
reply headers.  It will strip out your own email addresses from the
reply and set the From: to be an email of yours found in the original
message.

Note that this is built on top of the config change patch.
