[PATCH v3] VIM: Better reply handling with multiple emails

[Ian Main <imain@stemwinder.org>]

Fix 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.
