git-svn: check_cherry_pick should exclude commits already in our history
The merge-base between @$parents and $merge_tip may have been reached through a merge commit. This means that some commits that are ancestors of @$parents will not be ancestors of $merge_base. The mergeinfo property will not list commits that are ancestors of @$parents, so we need to explicitly exclude them. [ew: squashed and cleaned up test case from Steven] Signed-off-by: Steven Walter <stevenrwalter@gmail.com> Acked-by: Eric Wong <normalperson@yhbt.net>
