Yes: 24.3. So what is the consensus (if there is one)
to determine if something is a variable or not? - like
I said, in describe-function they put a condition on
obarray:

(or (get vv 'variable-documentation)
    (and (boundp vv)
         (not (keywordp vv)))))

`custom-variable-p' corresponds to "v" in the
interactive string, and that wasn't inclusive enough,
at least not in my case - which is - quite general, or
am I wrong?!

I think the above solution (the Elisp) should be put
into something like `variable-p' and then this should
be possible to indicate in the interactive
string. Perhaps an optional param (and/or prefix arg)
would indicate where to look if not in obarray.
