Hi Wolfgang,

Thanks for the (prompt!) answer.

I did not realize the wiki software did that.  On reflection I suppose that
is useful in many (most?) cases.  But I'd argue that it is not always a good
thing, such as in this case.  (If nothing else, it might mislead a n00b
into thinking that you should get output for text preceding \starttext.)

If you (or some other knowledgeable person reading this) don't (doesn't)
mind another question,...
Is the bullet symbol not from some font?  If so, why is that font loaded in
time to see the bullet?

And finally, might it make sense for the wiki software to do something like
this:
        if grep '\\starttext' <the-wiki-example-to-be-compiled> >/dev/null 2>&1
        then
            process the example from the wiki
        else
            augment the wiki example with \starttext and \stoptext
            process the augmented wiki example
        fi

Cheers.
                                Jim
