If the second argument is a directory, \cw{lns} will assume you want
a link created \e{inside} that directory, with the same filename as
the source file. If you supply more than two arguments, \cw{lns}
-will \e{expect} the final argument to a directory, and will do this
-for each of the other arguments.
+will \e{expect} the final argument to be a directory, and will do
+this for each of the other arguments.
(This behaviour is intended to mimic \cw{cp} as closely as
possible.)
