trivia bugfix

Can't the three lines:

  y = span->y;
  left = span->x;
  right = span->x + span->width; /* right is not in the span! */

simply be deleted? I don't see any use of those assignments.

Bumping priority to high to remind me to simply delete those
lines if I don't hear anything further.

Those three lines apparently can be deleted.
My original patch was just mechanically quick-hacked without further
looking at the code.
I did not test it as I do not currently have fbcon available here but
I have no doubts it would work.
Regards
