my motivation was "how else do we explain which ones are pathconf?",
which you need to know because all the others require 0 args, but
pathconf requires 1 arg. it didn't seem reasonable to do that in
--help, and although i considered something like adding '*' to the
pathconf ones, that breaks the traditional unix style that you were
going for but without actually fixing my problem...

not _everything_ --- just the ones that are defined (and i'm guessing
it uses '.' for the pathconf ones?).

but i can do that while you do something more useful :-) i'll fix the
"undefined" behavior too, since i found one caller that was expecting
it... (but i'll wait for you to push first, in case you'd made
additional changes.)
