I didn't mean a regression, but a change in behavior.  I've installed
the patch locally, and pressing TAB in *Packages* now goes from column
to column.  Before the patch, it went from package to package.  We can
either:

a) Accept the new behavior, as it is more intuitive in my opinion.
b) Override the binding in package.el, to preserve the original
behavior.

(The same may happen to other packages that inherit from
tabulated-list-mode.)

I'm in favor of the change.  If it's documented well in NEWS, it
shouldn't cause much trouble if packages need to adapt to it.
