The rewrite handler percent-decodes the path after expanding placeholders.
Regexp captures, usually taken from the already-decoded request path by
path_regexp, were inserted verbatim, so a double-encoded "../" or "?"
became a real separator or query string after path guards had run.
{http.regexp.*} values are now escaped like the other path-derived
placeholders (slashes preserved) when used in the path part of a rewrite.
Captures intentionally used to inject "?" into the path from a header or
other source must now set the query explicitly.
