Subject: Minor improvement in eval of unstoppable pawns promoting one ply apart.

Minor improvement in eval of unstoppable pawns promoting one ply apart.

Marco's new code for evaluating two unstoppable passed pawns where
one pawn promotes a single ply before the other tried to detect
cases where the pawn that promotes first could immediately capture
the pawn that promotes a ply later, but didn't work in cases where
the two pawns are on the same file. An example of this is the
following position:

8/8/3K4/2P5/2p5/3k4/8/8 w - -

With the new code, such positions are handled correctly.
