Marcel would know best, but he's currently otherwise occupied.

AFAIK the main problem with upgrading to Lucene 2.4.x was the bug in
2.4.0. The upgrade to 2.4.1 in revision 756442 seems to have been all
that was needed, and as you notice, revision 756444 looks more like
related cleanups.

The query functionality is reasonably well covered by the test cases,
so if your backport passes all the tests then it's reasonably safe to
use as-is.
