[mod_python] Sending back headers with 4xx responses

No, that's not it.  Either way the response code is sent back,
but not the headers.  It definitely appears to be a problem only
for 1xx, 4xx and 5xx codes.  For any 2xx or 3xx codes,
headers go through as expected.

At least for the 4/5xx codes, perhaps the problem is the way
Apache really does an internal redirect to the appropriate
error page?  Is there any way to pass information or headers
on to those?

Whatever the reason, I seem unable to send back a Content-Range
header for a 416 as recommended by the RFC.
