patch 9.1.0205: Cannot use modifiers before :-Ntabmove

Problem:  Cannot use modifiers before :-Ntabmove.
Solution: Check backwards from the command instead of checking from the
          start of the command line. Slightly adjust docs to make them
          more consistent (zeertzjq).

closes: #14289
