I think that the preceding 2/4 should cover your concern here, i.e. I
think that's not possible.

Indeed, but I believe (again see 2/4) that can't happen.

Yes. I almost changed it to the former in this re-roll, but as noted in
<220219.86y227fvz1.gmgdl@evledraar.gmail.com> thought it was better to
have it clear that this really wasn't a generic mechanism, we really do
need/want the actual "t" directory here.
