A slightly special case because other than the pydir only
synthetic code is involved (generated source). If you have
at least one "real" entry not relative to pydir it should work.
Anyway, i changed this in rev1610 - let's see if it causes
any problems (in py.test reporting).

The last entry is generated source, what you see if where it got generated.
By passing in a filter function you override the default filter
lambda x: not x.ishidden(). You can "AND" that in your lambda.
