The documentation for Co-developed-by is a bit light on details, e.g. it doesn't explicitly state that:
- Multiple Co-developed-by tags are perfectly acceptable - Co-developed-by and Signed-off-by must be paired together - SOB ordering should still follow standard sign-off procedure
Lack of explicit direciton has resulted in developers taking a variety of approaches, often lacking any intent whatsoever, e.g. scattering SOBs willy-nilly, collecting them all at the end or the beginning, etc...
Tweak the wording to make it clear that multiple co-authors are allowed, and document the expectation that standard sign-off procedures are to be followed. Provide examples to (hopefully) eliminate any ambiguity.

v1: https://lkml.kernel.org/r/20190320151140.32432-1-sean.j.christopherson@intel.com v2: Rewrite the blurb to state standard sign-off procedure should be followed as opposed to dictating the original author's SOB be last.
