git-svn: expand the svn mergeinfo test suite, highlighting some failures
As shown, git-svn has some problems; not all svn merges are correctly detected, and cherry picks may incorrectly be detected as real merges. These test cases will be marked as _success once the relevant fixes are in. Signed-off-by: Sam Vilain <[email protected]> Acked-by: Eric Wong <[email protected]>
