Should this comment read 'to the tail'? I get a bit confused about how to talk
about ordering when RLs are involved.

findCommonFL is quite similar to findCommonAndUncommon apart from working with Ident
rather than Eq2, right? The proliferation of similar functions makes me nervous about
complexity. But probably something for a future cleanup.
