`mark' func returning nil

[Kevin Ryde]

The docstring and manual of the `mark' func reads to me like it always
returns an integer, and the nil return is only if you use the FORCE arg.

But if I'm not mistaken nil is normal when the mark has never been set
in a buffer (eg. C-x b foo C-: (mark) => nil).  It'd be nice if that
could be clarified, since I didn't realize it until I'd written some
code expecting an integer, which bombed in a new buffer.

        * simple.el (mark): Clarify docstring, return is nil if mark not yet
        set.

        * markers.texi (The Mark): Clarify `mark', return is nil if mark not
        yet set.
