Better make this word //= 85, one thing less to modify when trying to
get hg work with Python 3. Or does hg have to support Python 2.1?

I'd think unpack('>%iL' % longs, text[0:longs*4]) would be slightly
better here, as no long string has to be created and parsed (the same
goes for pack)

BTW, Matt said that all C code was once implemented in Python, so
there probably is some base85 encoding.
