Currently you would have to use
$ hg status -uin0 | xargs -0 rm --
And then use find to remove empty dirs.

Cumbersome, error prone and not portable to Windows.

Some comments:

        act = True
        if opts['nothing']:
            act = False
could be written as:
        act = opts['nothing']
(as it doesn't matter if it is None or False)
or if you really want to have True/False:
        act = bool(opts['nothing'])

Additionally I'm not sure why you made from_command a static method
of Purge instead of just putting it in the module's namespace.

Instead of:
        if self._ui.verbose:
            self._ui.status(name + '\n')
you can simply use:
        self._ui.note(name + '\n')

And all this _relative_name/_split_path/_join_path is confusing me.
Maybe look at localrepo.py or dirstate.py what you can reuse?

Did you test all this on Windows?


If nobody objects I want to put this into Mercurial's hgext when the
code is ok, as I'd like to have this feature, too.
