No problem, I wrote the original code, so I was fixing it in parallel! Sorry
for changing your fix :-)

We should maybe improve the iterator at all (the StoredFields branch has a
FilterIterator already, which just has a matches() method) and make the
whole class available outside of tests? Its as useful as the other
FilterReaders in contrib/misc. You can use it to split an index vertically
(remove fields from an index by the usual IW.addIndexes(new
FieldFilterAtomicReader(...))
