When matching a pattern such as /^\.rtl/ against:

@media screen and (min-width: 50em) {
    .rtl .thing {
        color: red;
    }

   .another .thing {
        color: blue;
    }
}

Currently yields:

.rtl .thing {
    color: red;
}

but we should have the option to include the parent media query node, giving us:

@media screen and (min-width: 50em) {
    .rtl .thing {
        color: red;
    }
}

See #2 (comment)

@Extended selectors are being moved to the split stylesheet when they should be left behind.

In this example, I wish to move only .split-me to split-me.css:

// INPUT

// _demo.scss
%silent_shared {
    color: red;
}
.split-me {
    @extend %silent_shared;
}
.do-not-split-me {
    @extend %silent_shared;
}

// main.scss
@import "demo";

// OUTPUT - expected

// main.css
.do-not-split-me {
    color: red;
}

// split-me.css
.split-me {
    color: red;
}

// OUTPUT - actual

// main.css
// empty

// split-me.css
.split-me, .do-not-split-me {
    color: red;
}

Now you set from and to option only if source map is enabled. It is bad, because:

• PostCSS parser uses from option to show syntax error messages.
• PostCSS will try to autodetect previous map file with from options.

My config:

split_styles: {
    rtl: {
        options: {
            pattern: /\.rtl/,
            output: '_styles/main.rtl.css'
        },
        files: {
            '_styles/main.css' : '_styles/main.css'
        }
    }
}

grunt --verbose outputs:

Files: _styles/main.css -> _styles/main.css
Options: separator="", pattern={}, remove, mediaPattern=false, unwrapMedia=false, output="_styles/main.rtl.css"

Looks like the pattern is not recognised.

The option 'matchParent' works perfectly when a parent media query is present, but ignores rules that do not have one.

Allow the 'output' option to be 'false'

Use case would be to strip rules from the css, but not create a new file.
