Documentation update request: (0 if no Content-Length header) is incorrect

[sarenameas]

Hello,

In https://github.com/nodejs/http-parser/blob/master/http_parser.h#L309 the content_length states the following:

uint64_t content_length; /* # bytes in body (0 if no Content-Length header) */

This is not true in the latest version. I checked the content_length after the response has finished, and if there is no Content-Length header, this remains as ULLONGMAX. Could you confirm this is expected and update the documentation?

Yes, that's expected. I've opened #513.
