Format multi-line tokens on a single line

[bartveneman]

Some example I cooked up:

a {
  background: linear-gradient(
    red,
  10% blue,
20% green,100% yellow);
}

a.b
 .c .d
   .e .f {
color: green }

Actual output

a {
	background: linear-gradient(
    red,
  10% blue,
20% green,100% yellow);
}

a.b
 .c .d
   .e .f {
	color: green;
}

Expected output

a {
	background: linear-gradient(red, 10% blue, 20% green,100% yellow);
}

a.b .c .d .e .f {
	color: green;
}
