Re: Dangerous: delete-file deletes current directory as root!!

[Richard Stallman]

    Now, I'm not sure what `delete-file' should do.  Should it mimic `unlink'
    or should it first check that it is not called on a directory ?

I think delete-file should refuse to delete a directory.
That operation is very risky, and anyone who really wants to 
do it probably will do it from the shell.
I think if Emacs simply detects that it is a directory and
signals an error, it would be fine.
