Well, that's more of a merging criterion that a search criterion. At
any rate, while it's true that they can/could be merged arbitrarily
since they're not actually associated with any particular file offset
range, there isn't any indicator I know of now that would actually
allow this distinction wrt. mergeability to be made.
