Subject: [PATCH 2/2] pretty: use fmt_output_email_subject()
Date: Wed, 1 Mar 2017 12:37:07 +0100 [thread overview]
Message-ID: <58e05599-5dc4-9881-d8c0-89ad1f2e3838@web.de> (raw)
In-Reply-To: <20170228181719.t67abnnnsdcx2xfd@sigill.intra.peff.net>
Add the email-style subject prefix (e.g. "Subject: [PATCH] ") directly
when it's needed instead of letting log_write_email_headers() prepare
it in a static buffer in advance. This simplifies storage ownership and
code flow.
Signed-off-by: Rene Scharfe <l.s.r@web.de>

This slows down the last three tests in p4000 by ca. 3% for some reason,
so we may want to only do the first part for now, which is performance
neutral on my machine.
