Subject: `// @license` should be at the beginning of a line (mod whitespace)

Otherwise the following will be processed for @license / @license-end
method:

// foo.js
// // @license magnet:?xt=urn:btih:1f739d935676111cfff4b4693e3816e664797050&dn=gpl-3.0.txt GPL-3.0
// document.getElementById('bar');
// // @license-end
function foo(x, y) {
  console.log(x + y);
}

$ node ./utitlities/check-script foo.js

[
  true,
  '// // @license magnet:?xt=urn:btih:1f739d935676111cfff4b4693e3816e664797050&dn=gpl-3.0.txt GPL-3.0\n' +
    "// document.getElementById('bar');\n" +
    '// // @license-end\n' +
    'function foo(x, y) {\n' +
    '  console.log(x + y);\n' +
    '}\n',
  '\n' +
    'Recognized license: "GNU General Public License (GPL) version 3".\n' +
    'Script appears to be trivial.'
