If we do keep the default ignore list then it would make sense to add
these.  But I think the performance evidence plus the model simplication
of making them explicit is compelling.

This was discussed previously

and I'm going to go ahead and pull in Robert's changes.  In the future
we should also look at personal ignores; perhaps also at having a way to
script some defaults for bzr init.
