Another patch from Matt Kraai <kraai@alumni.carnegiemellon.edu>:
>
> The following patch allows ln -n to function like GNU.  It also fixes a
> typo with my previous patch to add support for ln FILE DIRECTORY.  And
> it removes some code that checks the maximum length of the filenames.  I
> can't figure out why that code is necessary.  Anyone know?
