No sign-off, no description.

This is a regression introduced by 53cad69 (post-receive-email: ensure
sent messages are not empty, 2010-09-10), I think.

This used to "exit 1" before 53cad69 and I agree with the patch that
signalling error with "return 1" is the right thing to do here.

This used to "exit 0" before 53cad69 to cause the program stop before
sending mails.  Again, I agree with the patch that signalling error is the
right thing to do here.

And this obviously is correct.

Kevin, care to review and Ack?  Alan, care to add a few lines of patch
description and sign-off?

Yeah, this is clearly my breakage; our internal version of this script is so different that it has become hard to backport fixes to the upstream version... or I just did a terrible job of it.

Alan, while you are in there fixing this, there is a remaining 'exit 0' in prep_for_email (at line 147) that should be 'return 1' instead.
