Resolve glob imports

[Yankovsky]

I have following files:
src/my.css

@import "vars.css";
* {
    color: $my-color;
}

src/vars.css

$my-color: red;

and index.css

@import './src/*.css';

When I run postcss index.css I get following result:

* {
    color: $my-color;
}

$my-color: red;

If I change the name of vars.css file to something like avars.css (which comes before my.css alphabetically) or if I use specific path in index.css instead of glob everything works as expected and the result is:

$my-color: red;

* {
    color: $my-color;
}

I think it is a bug and dependencies resolution shouldn't be broken by using globs.

I thought that glob pattern resolution works by first obtaining all files matching pattern and then processing them through usual resolution algorithm.

Funny thing is postcss-import pre glob removal didn't have that problem.

Could you describe imports resolution algo?
