I believe you mean that a symbolic link to a directory does not work as
expected. The "rm" manual page actually does not mention symbolic links
and what it does with them.
Currently delete("link") deletes the link, not the file it points to. I
think that is good. So we should do the same for when the symbolic link
points to a directory.
Hmm, would that require: delete("dirlink", 'd') ?
Or can it be done with delete("dirlink") ?
It appears "rm dirlink" works, so we best follow that.
