111 * Searches err.toString() for err.name + ':' + err.message,
112 * with possible whitespace on each side of the colon sign.
114 * We allow for no colon in case err.message was not provided by the user.
115 * In such a case, SpiderMonkey and Rhino currently set err.message = '',
116 * as allowed for by ECMA 15.11.4.3. This makes |pattern| work in this case.
118 * If this is ever changed to a non-empty string, e.g. 'undefined',
119 * you may have to modify |pattern| to take that into account -
