From d0aaa46fd3e53801346a4cadebf398f05d79780b Mon Sep 17 00:00:00 2001 From: Phillip Wood Date: Fri, 10 Nov 2017 11:09:42 +0000 Subject: commit: move empty message checks to libgit Move the functions that check for empty messages from bulitin/commit.c to sequencer.c so they can be shared with other commands. The functions are refactored to take an explicit cleanup mode and template filename passed by the caller.
