Small patch to keyword extension ('module' object has no attribute '_parse')

[Marcin Kasperski]

I just tried setting up keyword extension on some Debian testing box,
just to see things like:

  $ hg status
  *** failed to import extension hgext.keyword: 'module' object has no attribute '_parse'
  *** failed to import extension hgext.keyword: 'module' object has no attribute '_parse'

Or if one prefers details:

  python keyword.py
  Traceback (most recent call last):
    File "/var/lib/python-support/python2.4/hgext/keyword.py", line 93, in ?
      _parse = dispatch._parse
    File "/var/lib/python-support/python2.4/mercurial/demandimport.py", line 75, in __getattribute__
      return getattr(self._module, attr)
  AttributeError: 'module' object has no attribute '_parse'

I am not sure what exactly happened (previously installed keyword on
some ubuntu and debian stable and there everything went OK). But the
following tiny patch resolves the problem and makes keyword to work:
