[RFC PATCH] send-email: allow a custom hook to prevent sending email

From: Stefan Beller <sbeller@google.com>
Date: Dec 9, 2016, 20:34 UTC
Message-ID: <20161209203449.17940-1-sbeller@google.com>

This custom hook could be used to prevent sending out e.g. patches with change ids or other information that upstream doesn't like to see or is not supposed to see.

Signed-off-by: Stefan Beller <sbeller@google.com>

My first perl contribution to Git. :)

Marked as RFC to gauge general interest before writing tests and documentation.

Thanks, Stefan
