Functions returning length-spec

[roconnor@xxxxxxxxxxxx]

I can't find an example of a function that returns a length-spec.  Is
there some way of finding out how wide (literal "•  ") is?  This
will allow me to reverse-indent my bulleted items by the right
amount.  (Or maybe there's a better way to handle bulleted lists.)
