readlink: support --, -n always
POSIX will be standardizing readlink (just the -n option) and realpath (just -E and -e options): https://www.austingroupbugs.net/view.php?id=1457 Change things for readlink so that the POSIX-mandated -n and -- work even when disabling the non-standard (and partially non-working) -f when FEATURE_READLINK_FOLLOW is clear. POSIX also wants readlink to be verbose by default (if the argument is not a symlink, readlink must output a diagnostic); I did NOT address that one, because I'm waiting to see what the GNU Coreutils folks do: https://lists.gnu.org/archive/html/bug-coreutils/2023-03/msg00035.html Partial fix for https://bugs.busybox.net/show_bug.cgi?id=15466 function old new delta packed_usage 34538 34557 +19 Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
