mod_include now tweaks the subrequest output filter chain so that

only *subsequent* filters from the original request are inherited.
Previously, *all* filters from the original request were inherited.

Currently, any filter which runs a subrequest should do the same
thing (though a cleaner interface may be appropriate.)

With this change, subrequests are properly filtered much more often.
