Makes sense. I'd prefer
exe=`dmenu_path | dmenu ${1+"$@"}` && exec $exe
though to make sure dmenu is not passed an empty argument in case
dmenu_run is called without arguments.

Hmm, for few directories and lots of files this is indeed slightly
faster.

Not all sort(1)s have a -u option. However, the '&&' is a good idea,
as is the quoting.
