So, do you mean that nginx is meant to not have such "generic URI 
parsing function" at all?
Okay - do you think it's sufficient just to change
ngx_unescape_uri(&dst, &src, uri->len, 0);
to
ngx_unescape_uri(&dst, &src, uri->len, NGX_UNESCAPE_URI);
in the previous patch? (i.e. in 
http://www.coderain.de/nginx/nginx-0.8.52-xred.patch)

P.S: what's NGX_UNESCAPE_REDIRECT?
