Right. I saw that (but forgot about it - thanks for reminding me).
I think that's a mistake. What's gained by that? We already saw what is lost
by it.
BTW, the comment about deferring computation seems off base. I don't see any
computation deferral, but I do see computation caching. That's what is
important (and wrong), I think: `abbreviated-home-dir' is computed only
once.
