AssertionError with missing braces and multi-line description in @returns tag

[pabigot]

Reproduced with node-jscs, but from the stack trace I think the issue lies here.

The following source code:

/**
 * Description.
 *
 * @param {integer} v - value v
 *
 * @param {integer} w - value w
 *
 * @returns string - `v`
 * plus `w` as a string
 */
function f(v, w) {
  return (v + w).toString(16);
}

when processed with a .jscsrc holding:

{
  "preset": "google"
}

produces for me:

Error running rule jsDoc: This is an issue with JSCS and not your codebase.

1 code style error found.

Putting the missing braces around the type in the @returns statement fixes this, as does joining the two lines of the @returns description into one line, if that helps track down the origin of the problem.

Thanks for report. Looking at it.
