bug#19751: 25.0.50; scss-mode: interpolated variable filling

[Simen Heggestøyl]

The following Sassy CSS block is filled weirdly by SCSS mode when

pressing `M-q' at the beginning of the block:

@media #{$medium} {

    background: #f0f0f0;

}

Is filled to:

@media #{

    $medium

} {

    background: #f0f0f0;

}

As a more complicated example, the following:

@mixin firefox-message($selector) {

    body.firefox #{$selector}:before {

        content: "Hi, Firefox users!";

    }

}

Is filled to:

@mixin firefox-message($selector) {

    body.firefox #{

        $selector

    }:before {

        content: "Hi, Firefox users!";

    }

}

There seems to be an error with how SCSS mode does filling when

interpolated variables are involved, misinterpreting it as an ordinary

block.
