[patch 1.3] The http_protocol.c C-L + T-E patch

[William A. Rowe, Jr.]

folks, the same patch Paul/Joe worked out for 2.1, then 2.0,
should still probably fall on 1.3 even though proxy is not
affected.  Other modules surely could be hit.

Votes/Comments?  I think this is it for getting 1.3.34 out.
