Yep, that is *definitely* worth fixing.  And it turns out to be easy as well.
RequestDispatcher.include() doesn't change the path elements of the request
object, but it *does* store request attributes for the path elements of an
"include", so the controller servlet can easily tell whether this is the case
or not.  I will fix that in the 1.0 code base shortly.
