  (path_for_error_message): New function.
  (verify_write_lock): Use path_for_error_message. Add documentation.
  (mark_tree_conflict,
   drive_tree_conflict_editor,
   suitable_for_move,
   update_moved_away_conflict_victim): Use path_for_error_message.

  (bump_mark_tree_conflict): Split precondition and actual (failing) use case,
    which needs different handling for 1.9.
