Re: delete-file default to buffer-file-name if non-nil

[Richard Stallman]

    But it seems the most appropriate default value, in terms of what one might 
want
    to delete. Don't you think so?

That is true also, but it does not make the danger go away.

    2. Require confirmation if RET is hit with no file name in the minibuffer.

I like that solution.  But confirmation should be with y, not RET,
in order to follow Emacs conventions.
