hgweb: skip body creation of HEAD for most requests The body is thrown away anyway, so this just wastes a lot of CPU time. In the case of /archive/, this skips manifest processing and the actual file archiving, resulting in a huge difference. The most tricky part here is skipping the Content-Length creation as it would indicate the output size for the corresponding GET request.
