Is your feature request related to a problem? Please describe. I have found several places where the supported .editorconfig options are listed or used in examples. Each of these lists is different.

• https://prettier.io/docs/configuration.html#editorconfig
• https://prettier.io/docs/api.html#prettierresolveconfigfileurlorpath--options
• https://prettier.io/blog/2017/12/05/1.9.0.html#configuration

Describe the solution you'd like A single page with all of the current .editorconfig values that are supported, perhaps on the VSCode market place listing as well.

This might push development of more supported options.
