Modified Files:
        src/lib/libcurses: refresh.c

Log Message:
When performing a scroll, check the last line of the region is the same
on virtscr and curscr because the indexes past are supposed to be
one *past* the last matching line (they may actually match if the line is
at the bottom of the screen).  Iff they don't match reduce the scroll
region size by one so we don't scroll non-matching lines, also check
if the region is then 0 after the decrement and just return if it was.
