[issue2312] color extension broken on win32 with hg 1.6.1

[Pascal Quantin]

New submission from Pascal Quantin <pascal.quantin at gmail.com>:

With color extension activated on a windows box, a simple hg version raises
the following backtrace:
@ Dev> hg version
Traceback (most recent call last):
  File "hg", line 27, in <module>
  File "mercurial\dispatch.pyc", line 16, in run
  File "mercurial\dispatch.pyc", line 34, in dispatch
  File "mercurial\dispatch.pyc", line 165, in _runcatch
  File "mercurial\ui.pyc", line 505, in warn
  File "hgext\color.pyc", line 166, in write_err
NameError: global name 'orig' is not defined

The culprit seems to be changeset d8d0fc3988ca
