Done.  I just noticed that Carlos' entry just says:

Carlos O'Donell for his maintainership of the HPPA architecture and
maintaining @theglibc{} web pages.

I believe that's quite outdated.  How about:

Carlos O'Donell for his maintainership of the HPPA architecture, for
maintaining @theglibc{} web pages and wiki and for various fixes.

There probably should be something that reflects Carlos' and Joseph's
contributions to the task of herding cats since the steering committee
is dissolved, but I can't seem to come up with anything appropriate.
