The newer one is not so overgrown yet. I do wish we revert the part 
where next-error-function is buffer local, though, and then you could 
design this possibility as a user option. We discussed the approaches, 
but it comes out pretty complex no matter the way you look at it.

Umm, I don't think the request is anything so ambitious.

Charles has been asking for a ring to store the navigation locations 
visited by xref only.
