Now that you say that... I seem to have a very faint memory of a
discussion about this (not in _expand, I think, we had the problem
somewhere else). I think we found a solution which I can't think of
now and I don't know where to search for it either.

And the maling list archive seems to be defunct -- I always get zero
metches no matter what I'm searching for.

Hm. Anyone else remember this?

That aliases-inside--U-functions isn't that easy, I think (and there
may be cases where the function wants to have them expanded but the
user loaded it with -U, without thinking about this side-effect).
