FWIW, macOS uses '-O' to display file flags instead of '-o' (which has POSIX
semantics there).  Currently there is no way to get the equivalent of POSIX
-o output from ls, but breaking compatability for -o seems too large (as noted
in discussion in the review) vs this compromise that matches NetBSD and OpenBSD.
