File in trunk is fine, rest of docs also.

If a specially crafted request was sent, it is possible to crash mod_dav or 
mod_cache, as they accessed a field that is set to NULL by the URI parser, 
assuming that it always put in a valid string.

init functions for connection filters (doing an "init" once per
handler invocation makes no sense for a connection filter).  No longer 
run init functions multiple times per request if a subrequest is used.

* include/util_filter.h (ap_filter_rec_t): Clarify use of the init
  function pointer.

* server/config.c (invoke_filter_init): Drop ap_ prefix for private
  function; take a request_rec pointer and only invoke filters with
  matching request.
  (ap_invoke_handler): Adjust accordingly.

This one-line patch fixes a bug introduced since 2.2.15,
so it would be a particularly good idea to backport before $next-release.

I kept "back slash" when explicitely used in
comparison with "forward slash".

mod_rewrite: Allow to set environment variables without
explicitely giving a value.

Before this patch using [ENV=VAR] instead of [ENV=VAR:VAL]
silently drops the flag (it is added to the list of vars to set,
but then never actually set).
