[PATCH] post-receive-email: fix accidental removal of a trailing space in signature line

[Andy Parkins <andyparkins@gmail.com>]

post-receive-email adds a signature to the end of emails in
generate_email_footer().  The signature was separated from the main email
body using the standard string "-- ". (see rfc3676)

In revision a6080a0a44d5, Junio's "war on whitespace" removed the trailing
whitespace from "-- ", leaving it as "--", which is not a correct
signature separator.

This patch restores the missing space, but does it in a way that will
not set off the trailing whitespace alarms.
