Except that sometimes the user has those "oops that's not what I
meant" moments (and I think it's more often "I want to restore _file_
'one'"). One tricky thing in this situation is (to me) one/two and
one/three are untracked and we generally do not touch them unless
Technically 'one' is still tracked (even if it's a directory) so what
we're doing is right. I'm just not sure if there's some big surprise
factor here. And whether it's better to pause and double check with
the user before deleting everything.

Yes. It makes me really want 'git restore --diff [--stat]' just to
show what's going to be restored. A careful user may see something
unexpected and examine more before really doing 'git restore'.
