like i said, i'm not sure. no errors in the plain `ls` case seems
obvious. but i notice for example that coreutils silently does `ls -F`
correctly for your example (presumably because all entries are
directories, so the dt_type it got from readdir was sufficient). and
that "do i have enough valid data?" seems a bit hairy. and may explain
why you seem to get different results to me... coreutils still working
this out. (i haven't looked at ls.c to see how many places would have
to be touched, though, so maybe i'm imagining it worse than it is.)

(there is actually a new mac mini this year, but it's surprisingly
expensive while still being very weak --- "better than the old mac
mini" is probably the best you could say. as an owner of one of the
early mac minis, i was disappointed.)
