Files in top directory not backed up with default maxsize=-1

In "Branch for collecting patches for 0.10.5" (Revision 18, bzr branch lp:sbackup/0.10.5).

New default value of maxsize = -1 in /etc/sbackup.conf should not exclude any files based on size. One part of logic checks for

   maxsize > 0 and s.st_size > maxsize

other part just checks

   s.st_size > maxsize

and therefore it skips all files there when maxsize = -1

See attachment for fix.
