commit: move editor outside transaction...
commit: move editor outside transaction The commit editor is now invoked before files and manifest are committed. The editor is now run with only the wlock held and aborting an edit no longer requires rolling back a transaction. Changes to files during a commit still result in undefined behavior. (This is preliminary work for committing subrepositories)
