Spurious semicolons do funny things to output

[eevee]

$ python -m scss --style expanded <<< 'p { color: red; }; p { color: blue; }'
p {
  color: red;
}

; p {
  color: blue;
}

Not really down with having that semicolon as part of a selector. It breaks the entire rule.

Obviously this is bogus, but Ruby ignores it, and anyway we (a) support rules at top level and (b) should just ignore "empty" rules like this.

No longer happening, for whatever reason.
