Missing JSDoc function syntax

[kungfooman]

Example:

  /**
   * @param {Buffer|string} file
   * @param {string=} encoding - ignored if file contains a Buffer
   * @param {function(Error, object): void} callback - Call this function (optionally with an
   *          error argument and data) when you are done processing the supplied chunk.
   */
  transformStream._transform = function(file, encoding, callback) {
    var error = null,
        output = doSomethingWithTheFile(file);
    callback(error, output);
  };

TypeScript supports parsing this syntax natively, Babel-TS doesn't... as usual.
