I think in the future it will make sense also to separately install the most
recent version of allout.el even in conjunction with Emacs-22.  So I agree
with Ken's motivation and think that keeping the `put' outside of the
comment is the right thing to do.

Yes, but if the package is also distributed separately, the other form makes
more sense.
