[Feature Request] Please wrap ap_make_content_type

Hi.

I have found that the content type header, that is sent is not the one
from $r->content_type. Instead it is
$r->make_content_type($r->content_type). This is (as far as I understand
it) because of the meaning of default (use, if no other is set).
make_content_type adds the default charset that has been set with
AddDefaultCharset directly before sending the header.

In some situations it is necessary to know the charset that would be
sent. I found this while tracking down a charset bug in my module
(Cindy::Apache2). This runs the libxml2 parser on the content returned
by a subrequest. To do this correctly it must know the charset, which in
a correctly configured apache is the charset that would be sent over the
net.
  
It should be easy to do.

As Torsten Foetsch said:
!MODULE=Apache2::HTTPCore
>ap_process_request
>ap_make_content_type
>ap_core_reorder_directories
>ap_index_of_response

It should be enough to change that to

MODULE=Apache2::HTTPCore   PACKAGE=Apache2::RequestRec
>ap_process_request
 ap_make_content_type
>ap_core_reorder_directories
>ap_index_of_response

Thanks,
Joachim
