This is a fork of postcss/postcss-import, which disables that files get
inlined which are specified using the url() expression.
In some cases we want to be able to link to externally managed
CSS files. We think, the most intuitive way is to take
url() expressions as explicit user intention.
With our patched plugin the following does not get inlined
@import url('my-shared-library.css');
as opposed to
@import 'my-shared-library.css';
