>
> If the index was created with autoCommit false, and more than 1
> segment was flushed during the IndexWriter session, then the shared
> doc-store files are incorrectly duplicated in
> IndexCommit.getFileNames().  This is because that method is walking
> through each SegmentInfo, appending its files to a list.  Since
> multiple SegmentInfo's may share the doc store files, this causes dups.
> To fix this, I've added a SegmentInfos.files(...) method, and
> refactored all places that were computing their files one SegmentInfo
> at a time to use this new method instead.
