93u+m update

[Martijn Dekker]

For those not already in the know, a few updates:

1. I've successfully rebased my fork off of att/ast and development is
continuing uninterrupted. The more I think about it, the more this seems
like it was the right thing to do. With a direct hash chain to the
original repo, the complete AST history is now in my own git repo, so
any changed or deleted stuff can easily be checked out or diffed from
old commits. This makes it much easier for the public to verify the
integrity of all the changes, plus it makes it easier for me to restore
something later (as I did with pty the other day... the pty.sh
regression tests for the interactive shell now work). No slight against
the ksh-community folks or anyone else is intended, and everyone remains
just as welcome to contribute/participate as before.

2. A generous donor gave me sole control over a shiny and pristine
GitHub organisation account named ksh93 that they were sitting on, so
I've moved everything there. Thank you very much, you know who you are.

3. Johnothon King has turned into a regular contributor, so things are
moving along even more nicely :) I hope we get more contributors.

4. Someone added me as a moderator of this list. Since it wasn't
Siteshwar (who resigned as moderator the other day) and Kamil is the
only other listed moderator, I suppose it was Kamil. Thanks for the vote
of confidence!
