forbidding --fix with --stdin makes it incompatible with vim-autoformat

[gautaz]

vim-autoformat documentation states:

The formatprogram must read the unformatted code from the standard input, and write the formatted code to the standard output.

I guess this limitation (forbidden --fix --stdin) comes from eslint but I still ask in case there is anything that can be done to work around the limitation on xo's side.

I just followed ESLint's lead, but in hindsight it doesn't make sense. Added in #164. Please try it out and report back :)

@sindresorhus Just tried your stdin-fix branch, works like a charm with vim-autoformat!
Thanks! :-)

@gautaz Cool. Would you be willing to submit a short instruction on how to use the VIM autoformat and XO? Here: https://github.com/sindresorhus/xo#vim

Done in #165, hope it is enough.
Additional configuration might be needed in case you want to use the XO's module from the current project but it seems a bit out of scope (for an example see this autoformat config using these utilities).

XO already handles that. If you call the global XO binary and there's one in your project, it will defer to that one instead.

Gosh! If only all linters could do that ;-).
