revset: add partial support for ancestor(wdir())

It's easy, so let's make it happen. I'm not certain if 'wdir() &' should
be required. ancestors(wdir()) works without it, but ancestor(wdir()) doesn't
as of now. That's the issue of fullreposet.__contains__() vs __and__().

from __future__ import absolute_import

from mercurial.i18n import _
from mercurial import (
        changegroup,
        error,
        extensions
    )

def abort(orig, *args, **kwargs):
    raise error.Abort(_('this is an exercise'))

def uisetup(ui):
    extensions.wrapfunction(changegroup, 'getbundler', abort)
