OK, based on that I have two possibilities.  The first is good if there is
no contradiction between "conformance" and "depature from the spec" in this
instance.  Otherwise, the second is probably better.

1. If v is null or undefined, JS_ValueToObject assigns NULL to *objp and
returns JS_TRUE. This is a known departure from the ECMA 262-3
specification, which was written after SpiderMonkey.

2. If v is null or undefined, JS_ValueToObject assigns NULL to *objp and
returns JS_TRUE.
