patch: fix sort() comparator argument

'hg import' fails under Python 2.3. The name of the compare function parameter in the call to list.sort() is 'cmpfunc' in Python 2.3 and
'cmp' in Python 2.4+. Passing the compare function as a named parameter is therefore problematic.

#!/bin/sh
#
# revlog.parseindex must be able to parse the index file even if
# an index entry is split between two 64k blocks.  The ideal test
# would be to create an index file with inline data where
# 64k < size < 64k + 64 (64k is the size of the read buffer, 64 is
# the size of an index entry) and with an index entry starting right
# before the 64k block boundary, and try to read it.
#
# We approximate that by reducing the read buffer to 1 byte.
