Mercurial 1.8.3 on Jython 2.5.2

[Sébastien Deleuze]

Thanks Matt, you're right.
The issue occur during following test in util.py:

if os.name == 'nt':
    from windows import *
else:
    from posix import *

In Jython, os.name return java, so I have replaced current code by
"from java import *" for the moment.

It now produces a new error :
C:\jython2.5.2\bin>jython ./hg
Traceback (most recent call last):
  File "./hg", line 36, in <module>
    mercurial.util.set_binary(fp)
AttributeError: 'module' object has no attribute 'set_binary'
