ECMA Section: 15.4.4.3-1 Array.prototype.join()
Description: The elements of this object are converted to strings and
these strings are then concatenated, separated by comma
characters. The result is the same as if the built-in join
method were invoiked for this object with no argument.

Reason: See http://bugzilla.mozilla.org/show_bug.cgi?id=155285
ECMA-262 Ed.3 Section 15.4.4.5 Array.prototype.join()
Step 3: If |separator| is |undefined|, let |separator|
be the single-character string ","
