Or, if you use Bikeshed, it's just the HTML tags <ins> and <del>. For
example:
https://github.com/Quuxplusone/draft/blob/29d1609da4182504dec7ada25b0700246bb7d86a/Makefile#L12
https://github.com/Quuxplusone/draft/blob/29d1609da4182504dec7ada25b0700246bb7d86a/d2266-implicit-move-rvalue-ref.bs#L529-L552
produces
https://quuxplusone.github.io/draft/d2266-implicit-move-rvalue-ref.html#wording

Even with Bikeshed, copy-pasting the standard text and marking up the diff
is still a manual process; but it *looks* pretty nice IMO, at both the
source level and the finished-product level.

HTH,
