I've always been told that email text length should be limited to 72
characters. I did some more research this morning in preparation for
sharing this and I find that according to RFC 2822 it should be 78
characters. I then continue to find more and more discussion about how
it "doesn't matter" or "use whatever you want".
In any case, below is a tiny patch to configure vim to wrap text at 72
characters. This patch is specific to the initial file that is used at
sup-config, but the same line could be edited in your local
.sup/config.yaml.
In any case, see the example below to configure your textwidth.
