Log Message:
Update to 8.0.2

Changelog:
8.0.2:
Version 8.0.2 contains two small bug fixes: proper handling of pages
with no content, and better handling of files with loops following cross
reference tables.

8.0.1:
This is a very minor update from 8.0.0. It just contains two small
enhancements that missed the train: handle zlib streams with data checksum
errors, and, in the command line tool, allow specification of page numbers
counting from the end in page ranges.
