From a0a68b99d131741c1867cff321424892838fc4b3 Mon Sep 17 00:00:00 2001
From: Yann Ylavic <ylavic@apache.org>

Subject: [PATCH] mod_rewrite: Better question mark tracking to avoid
UnsafeAllow3F. PR 69197.
Track in do_expand() whether a '?' in the uri-path comes from a literal in
the substitution string or from an expansion (variable, lookup, ...).
In the former case it's safe to assume that it's the query-string separator
but for the other case it's not (could be a decoded %3f from r->uri).
This allows to avoid [UnsafeAllow3F] for most cases.
Merges r1919325 from trunk
