From f4ee3eb68906f079dea45de4f1bbb03d68189eb3 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 12 Apr 2006 13:10:27 -0700 Subject: [PATCH] stripspace: make sure not to leave an incomplete line. When dealing with a commit log message for human consumption, it never makes sense to keep a log that ends with an incomplete line, so make it a part of the clean-up process done by git-stripspace.
