Support .config/config folder lookup

👋 @davidtheclark

@postcss-loader got a few requests to support setting a custom config path for postcss.config.js lookup and most of the folks especially wanted to store them in a separate .config/config folder somewhere in their project.

While thats totally fine and works for now, on the other hand it ignores/devalues the reason/benefit behind actually autoloading the config without the need for any additional ‘setup’ 😛 . So maybe there is a compromise possible to enable additional search in .config/config folders while walking the file tree.

|– (.)config(<---)
|   |– postcss.config.js
|– client
|   |– (.)config (<---)
|   |   |– postcss.config.js 
|   |– styles
|        |– index.css (search starts here)
|        |– postcss.config.js (supported)
|– gulpfile.js
|– webpack.config.js

If you are basically ok with it, but don’t have the time/interest to do it, coordinating me to the location in the source for getting started would be appreciated 😃

I had talk with Babel developers and they didn’t like the idea @hzoo

But I think people want some solution

@michael-ciniawsky This is now possible with v5, using the searchPlaces option. I added this use case to the examples in the readme 👍
