Servlet forwards from servlets with pathinfo mishandled

This is related to bug 455 . Following advice there, to overcome that bug I built from trunk, which partly solved the problem with servlet forwards to JSPs.

The remaining difficulty is that servlets invoked with additional path info are mishandled. It I have a servlet at "/rss/*" and I invoke it as "/rss/news" (with /news being pathinfo), then try to forward to "news.jsp", it dies trying to find "rsss.jsp". Apparently the base part of the servlet path is being overlaid on the beginning of the forwarding string.

If I change the servlet to handle only "/rss", it works fine -- but I can't use pathinfo.
