Sorry, I missed the `or' in your first mail. I agree that it's a good
idea to remove the burden from the output page functions to always
return a number, so I've changed the expander function accordingly.
I've used `when' instead of `if' which makes it clear that there is no
`else' part.
In any case, the change was not really necessary for the current set of
output page functions because they all return a number. I've just made
it so that there will be no problems with functions which might be added
in the future.
