This is a manifestation of the simplistic parser.  It thinks that
strings and numbers are distinct.  mark, since it needs to handle
complicated values, requires strings.  And a number isn't a string.

There are many things that could and should be improved in the parser.
This one seems easy to live with so I suggest fixing the manual so
that users don't get surprised.
