Summary: chunked trailer without Trailer header throws error

Initial Comment:
An http chunked message with a trailer element (e.g. Content-MD5) but without a corresponding Trailer: Content-MD5 header generates a curl error. (chunky processor #3 I believe).

The message is legal if not ideal, so it shouldn't throw the error. RFC 2616 makes the inclusion of the Trailer header a SHOULD and in no way does its generation or omission change the syntax of the chunked encoding or the legality of including trailers there.

Message:
You're right. There's no attempt to handle the trailer if the Trailer:
header was not present.

I'll work on a fix.
