The binhex module is buggy in py3k, witness the following example (it
works ok on trunk):

>>> binhex.binhex("README", "testA")
>>> binhex.hexbin("testA", "outA")
>>> binhex.binhex("LICENSE", "testB")
>>> binhex.hexbin("testB", "outB")
Traceback (most recent call last):

The bug is due to bytes-indexing returning an int in py3k while it
returns another bytes object in trunk. Here is a patch. I don't know how
to reliably test for it, though.

Believe it or not, the failing test is already in svn:

Well, failure or success of the current tests seems to rely on the
length of the filename being tested! :-)

Fixed in r73747 and r73748.
