Here's a fix. Can't think of the best way to code it, though:

1. Take r->path_info. Match it to the end of r->uri.
2. Find the point at which r->path_info and r->uri diverge (or
   r->path_info runs out of characters). Make the matching part of
   r->uri PATH_INFO, and the rest SCRIPT_NAME.

This should fix his problem. In his setup, r->path_info is
"/ivan/test-cgi", which matches only the last 9 characters of
"/ivan-cgi/test-cgi". So PATH_INFO becomes "/test-cgi" and SCRIPT_NAME
becomes "/ivan-cgi".

Sounds like it should work to me, and shouldn't break anything existing.
