_intlist seems to assume the given revs are fine.  I wouldn't be 
surprised if just passing a rev number also just created a set with the 
rev in it without checking if it's filtered first.

filelog() might have the same issue, since it returns linkrevs 
directly.  Though it uses filter instead of &, so it's probably ok for now.

It might be worth having an exception or debug assert or something for a 
bit to flush out issues?
