Won't work. 'ls -o' is already a valid command, so 'ls -fo' is the same
as 'ls -o -f' or 'ls -f -o'. You can't start a long-option name with a
single dash; at least, not in coreutils which uses getopt_long() (there
are some exceptions, like gcc, which use getopt_long_only() for
historical reasons, and which therefore can spell long options with a
single dash if there is no ambiguity, but use of getopt_long_only() is
not recommended in new programs).
