Leading withspace in a styl produces a leading ; in the generated css

[thomas-rager]

Accidentally I produced a file with only one spacer in the first line, this leads to a ; in the generated css. The example doesn't show it because github strips the source-code... please add a spacer and a break before the button to test it.

button 
  background-color: green
  width: 150px
  height: 150px

;

button {
  background-color: green;
  width: 150px;
  height: 150px;
}
