Seems like this can be merged since it's mentioning the option and is how cljfmt formats too.

I'm fine with the suggestion, I just want to avoid mentioning specific tools in the guide, as their configurations are not set in stone. We should use some neutral language here.

Btw, cljfmt uses 1-space indents by default (as currently suggested in the guide).

I've added a sidebar about this in this section https://guide.clojure.style/#one-space-indent I'll see how I can add some anchor directly to it.

Cool!

I think this is good explanation of the alternatives.

Note about list literals, Vim has a special case for lists starting with a number, items are intended with single space. But the problem does indeed appear with other lists, even after quote or syntax-quote, which makes sense, as quoted list could also be code. Probably no reason to mention this, though I wonder if the example can confuse someone, as Vim doesn't indent the examples like that.

Thanks for the feedback! I'll polish the wording later.
