Emacs 22 branch created.

[Chong Yidong]

I've created the Emacs 22 branch, which has CVS tag EMACS_22_BASE.
(I'm not sure of the reason for shouting, but it seems to be
traditional.)

Note that you need to use "-r EMACS_22_BASE" to apply your changes to
the branch.  If you want to work in the branch, I believe the easiest
way is to do

cvs up -r EMACS_22_BASE

in your working directory, which will move it to the branch;
subsequent commits will then apply to the branch.

Since the python.el issue doesn't seem likely to be resolved in the
near future, I will go ahead and remove it from the branch.  Then I
will roll the 22.0.99 pretest; it should come online in a couple of
hours.

Thanks.
