From e5138436ddd4b5f75c1e910f6b844e4fcf91343d Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 6 Nov 2009 23:06:06 -0800 Subject: [PATCH] builtin-commit.c: fix logic to omit empty line before existing footers "commit -s" used to add an empty line before adding S-o-b line only when the last line of the existing log message is not another S-o-b line, but c1e01b0 (commit: More generous accepting of RFC-2822 footer lines., 2009-10-28) introduced logic to omit this empty line when the message ends with a run of "footer" lines, to cover S-o-b's friends, e.g. Acked-by. However, the logic was overzealous and missed one corner case. A message that consists of a single line that begins with Token + colon, it can be mistaken as a S-o-b's friend. We do want an empty line in such a case.
