During development of pybackup, a bug in the python library fnmatch.py
module was found. This bug was reported along with a patch against the
Python v2.0 source. A modified patch was accepted into the new releases of
python. The original patch against Python v2.0 is supplied as
"fnmatch.py.patch", along with the patched version of "fnmatch.py".

Note that this application no-longer uses fnmatch, and instead uses the
extended version efnmatch.py.
