The only thing get_access_str() printed apart from the permissions was
whether it's a directory or not. But I'm very certain that it should be
identical to ls. Thanks for the pointer to the relevant part of ls,
attached is a patch moving it into a library function.

I like that approach. Attached is another patch removing unimplemented
options/formats and doing a bit of cleanup (mainly of the help text,
which has some resemblance with the GNU manual page).
