Our E-Mails probably crossed, my initial motivation for just-submitted
http://lore.kernel.org/git/cover-0.2-00000000000-20210412T105422Z-avarab@gmail.com
was going to CodingGuidelines, and vaguely remembering that there was
some other C99 thing that wasn't listed there, and then (re-)discovering
the recent variadic macro commit from Jeff King.

As noted there maybe 2/2 of that is too aggressive, but in that case it
would make sense to have a V2 of that which just carved off the
CodingGuidelines change.
