So really what needs to be done here is to make ELSIF chains explicit in

left-recursion.
So I'm going to go off and do that, but I wonder whether anyone thinks
this is sufficiently important to back-patch.
This doesn't look like a bug to me, just an unoptimal implementation. So
-1 for backpatching.
