I looked at the tutorial, but I didn't find any code example that
would contain an order_by call containing a space after the minus
sign. If there is such an example, could you point it out, so we can
fix it?

I'm not entirely certain which template you are referring to here,
since the third part of the tutorial iterates on the template for
polls/index.html, but assuming you mean the first version, both
"{{ question.id }}/" and "/polls/{{ question.id }}/" would be correct,
as long as you use the same URL patterns as described earlier in the
tutorial (i.e. if the correct URL is /polls/<id>/).
