r309232: Fix an obvious typo.
r309233: Eliminate variables that are computed, assigned but
         never used.
r309234: pages and psize are always assigned, so there is no
         need to initialize them as zero.

+POS1, -POS2 to -kPOS1,POS2, so that sort +0n gets translated to sort -k1,1n
as it is expected
