Incorrect @import output when there is an empty selector group and --skip-advanced

[exogen]

Given this simple CSS:

@import url('//fonts.googleapis.com/css?family=Domine:700');

body {
  color: #000;
}

body h1 {
  font-family: 'Domine';
}

cleancss --skip-import --skip-advanced will give the expected output:

@import url(//fonts.googleapis.com/css?family=Domine:700);body{color:#000}body h1{font-family:Domine}

However, if the @import is followed by an empty selector group (including when the group has only a comment):

@import url('//fonts.googleapis.com/css?family=Domine:700');

body {
  /* comment */
}

body h1 {
  font-family: 'Domine';
}

cleancss --skip-import --skip-advanced will omit the @import altogether:

body h1{font-family:Domine}

Without --skip-advanced, the output is as expected – the @import remains, but the body group is omitted. I would expect the same output with --skip-advanced.

Fixed in 1b59c1e - 2.1.6 is out with the fix too.

Thanks for raising it!
