Toot

The WG14 (C) meetings ended yesterday and I'm happy to report on two of my papers:

We now know how to add one to something, which is a welcome change (no implementation has to do anything, just purely a funny wording cleanup): https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3323.pdf

More importantly, zero-length operations on null pointers are no longer UB, which closes a ton of problematic UB in practice around things like memset(null, 0, 0); or null - null: https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3322.pdf

@AaronBallman is the monospaced font used in those papers somehow prescribed, or could a more sensible one be used?
