Creating a git branch for cond*

[Alan Mackenzie]

Hello, Richard, Eli, and Emacs.

Richard posted some embryonic code for cond* a little over a week ago.

To move things forward, I propose creating the git branch
feature/condstar, and incorporating the new code into it in
lisp/emacs-lisp/condstar.el.  This will enable its development to happen
more systematically and rapidly.

Does anybody have any objections?
