Would it not be nice if commands could be made (safely) available through the
bzrlib library?  The way I would be inclined to do it would be to add a
"context" parameter to a command's __init__, and to use it in particular to
replace the many hardcoded occurrences of u'.' (e.g. by self.context.root).

Is this a good/bad idea?  what else would need careful handling?
