That sounds good.

Yes, I think add could do with a good scrub out; I may do it this
week.  What I had in mind basically is that there would be a core that
generates a list of to-be-added files, and then we connect up various
callbacks to that.  At the moment we have this strange 'reporter'
thing which seems like it would almost be enough to set whether things
are actually added or not.
