I was reading
http://www.open-std.org/jtc1/sc22/wg14/www/abq/c17_updated_proposed_fdis.pdf

which is a draft and unofficial, so yours is more correct.
(looks like a lot of s/17/18/ will have to be done elsewhere...)

There's not going to be many references to it like C11 because it
doesn't add new things, only makes changes to existing stuff.

I made the first reference to newer-than-C11 to document some change.
It's not critical, it just felt like the right change to do.
