From ae901090f715fe6e5f589b4d92ec87b74429ed1b Mon Sep 17 00:00:00 2001 From: Vitor Antunes Date: Sun, 20 Feb 2011 01:18:24 +0000 Subject: [PATCH] git-p4: Improve rename detection support Only open files for edit after integrating if the SHA1 of source and destination differ from each other. Add git config option detectRenames to allow permanent rename detection. This options should be set to a true/false value. Rename "detectRename" variable to "detectRenames" to make it more coherent with the description in git man pages, which always use plural.
