Hi Matthieu,

I like this, and I am happy to see that it has been accepted.

I do wonder if we can go a step further and use an associative array for
ns_list (maybe renamed).  I think this would reduce remove_ns_list to
something like:

	unset ns_list["$item"]

OTOH, perhaps this breaks with older versions of bash that we still
care about.
