Unequal: run check_complete() after a hint move.

A user sent in the game id
  7:0,0L,0,0,0L,0L,1,0U,0U,0D,0UD,0,0,7,0,0D,0,0D,0,0,0,0,0,0,0,0,0,0D,0,0,3,0,0U,0,0,0,0,2,6,0,0U,0,0,0,7,2,0,0U,5L,
starting from which, one press of 'h' will fill in a 2 in the top left
corner and possibilities 345 to its right; if you then fill in 5 there
and press 'h' again, the hint system fills in the whole of an apparent
solution which isn't the one a proper use of the Solve feature would
give you - except that it's not actually a second solution, because
one < clue on the top row is violated. Without this fix, that < failed
to light up red, making the puzzle look ambiguous if you're not paying
enough attention to spot it.
