Improved patch

I created a patch similar to Craig's that instead modifies the MAX_MAP_SIZE
value (using a new "max_map_size" variable) which is based on the current
file's block size.  This means that we get more consistent sizing (since "len"
can vary) and that the sequence of window_size checks works out as originally
intended (maxing out at either the end of the file or at offset + len,
whichever is greater).
