I would like to change the tab-size from 8 to 4. I realize it's not strictly a normalization, as all browsers use 8, but it would improve the experience for everyone, so I think it's worth an exception. 8 is just a really really bad default. It has, for example, made tab-indented code on the web unreadable (isaacs/github#170).

I propose adding the following:

:root {
	-moz-tab-size: 4;
	tab-size: 4;
}

Using :root so users can easily override it on a per-element basis.

Thoughts?

(If you 👎 please also share your thoughts on why)
