Good point - PIDL is already mentioned at the top of COPYING in this way.

Now the question becomes, are we legally required to list *all*
additional licenses in COPYING, or only when the license itself
requires it? There are currently a couple of licenses which we carry
but aren't listed in COPYING, in addition to GPLv3 (html2text.py) and
GPLv3+ (PIDL) which is mentioned but not included.
