If some of the features are a logical unit, you can test for one
feature and assume that the others are present if it is.

There are a lot of broken programs, then.  GNU Emacs is one of them,
for example: its dired mode parses 'ls' output.

Also, I worry that the resulting 'ls' output would be wider than 80
columns too often.

I think it'd be OK to muck with "dir" and "vdir", though.  People
could get the behavior that you want with "vdir" or "dir -l", say.

I think one switch would be OK, at least at first.  You might want
to call it --hurd-extensions, perhaps?
