merge: reuse 'r' action code for 'rm' actions in recordupdates()

The 'r' and 'rm' actions behave the same in recordupdates(), and the
'm' (merge) action has already caused the move source to be stored
away, so we can safely remove the file a little earlier (where 'r'
actions are being acted upon).
