From 6d167fd7ccb84f07a0bd57d8e188a651e913b158 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Wed, 1 Mar 2017 12:37:07 +0100 Subject: [PATCH] pretty: use fmt_output_email_subject() 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.
