The above definition is not wrong, but it have unneeded code.
However the unneeded code explain clearly what happen.

Yes.
Because the name of this function (i.e directory-file-name), i didn't think
to call it on a filename, but it return the filename yes.
Maybe confusion with file-name-directory.
(always need to look manual when using all these file-name-*,
directory-file-* etc... functions)

Adding a basename function is just a first step to simplify all that.
