I just whipped up a varnishtest case, and it seems to work in -trunk:

        test "random test"

        server s1 {
                rxreq
                expect req.url == "/foo"
                txresp
        } -start

        varnish v1 -vcl+backend {

        sub vcl_recv {
                if (req.url ~ "(.*)%25[0-9a-fA-F]$") {
                        set req.url = regsub(req.url, "(.*)%25[0-9a-fA-F]$", 
"\1");
                }
        }

        } -start

        client c1 {
                txreq -url /foo%a
                rxresp
        } -run

###  c1   Connect to 127.0.0.1:17621

Never attribute to malice what can adequately be explained by incompetence.
