Well all of the following have that behavior:

$ grep -l parse_long_options *.c | sed 's/.c$//' | fmt
basename chroot cksum dd dirname echo expr getlimits hostid hostname
link logname nice nohup printf setuidgid sleep sync test timeout tsort
unlink uptime users whoami yes

The reason is that parse_long_options() only parses
options when there is a single option passed to the command.
It does this on purpose so as not to effect options that
may be passed on to further commands or requiring users
to specially mark such options.
