From e234ac9d47b6618f7b7338f95f34d0b70782e4cb Mon Sep 17 00:00:00 2001 From: Michael Contreras Date: Sat, 30 Mar 2013 18:06:42 -0400 Subject: [PATCH] git-svn: avoid self-referencing mergeinfo When svn.pushmergeinfo is set, the target branch is included in the mergeinfo if it was previously merged into one of the source branches. SVN does not do this. Remove merge target branch path from resulting mergeinfo when svn.pushmergeinfo is set to better match the behavior of SVN. Update the svn-mergeinfo-push test.
