lastIndexOf improved patch

This patch should fix some of the problems seen in the previous iterations.
However, there's a confusing bit in the docs about what to do when the index is
negative:

"Note that even when the index is negative, the array is still searched from
back to front. If the calculated index is less than 0, -1 is returned, i.e. the
array will not be searched."

The second sentence seems to contradict the first (is the array searched or
not??). This patch went with the second sentence. Firefox, it seems, went with
the first.

When that mess gets sorted this patch will need a changelog & a test case.
