^X feedback and end of game disclosure reported
 Your two weapon skill {is,was} [also] limited by being <skill rating>
 with with <secondary weapon>.
when the skill rating for the secondary weapon is/was less than the
skill rating for two-weapon combat.  The corresponding message for
primary weapon did not duplicate the word "with".
