 I've seen some situations where the newly added OrPostList::check() method
 returns the incorrect value for "valid", resulting in some documents being
 skipped from the search results.

 I have a patch which fixes the problem in a large production database, but
 have not yet produced test cases for it.

 This method was new in SVN since 1.2.0, so I believe the problem isn't in
 any released version.  We need to fix this before the next release,
 though.
