1) permissions aren't respected in the merge script (primarily because they're never passed in to it in the first place). Fix that and also check for permission conflicts in the merge 2) the delete of a file in both branches may indeed be just that, but it could also be the indicator of a rename conflict (file moved to different locations in both branches), so error out and ask the committer for guidance.
