Hi Tassilo,

next time I shall read the source code _before_ posting. ;-)
Function set-fill-column contains the following comment:
;; Disallow missing argument; it's probably a typo for C-x C-f.

So the point is that plain "C-x f" should produce an error because it
is too similar to "C-x C-f". No default, and no further query.
