Why not have 1 command, customize-changed, that by default shows the
unsaved variables (like customize-customized does now) but with a prefix
arg shows either the saved variables (like customize-saved) or both
saved and unsaved variables (like customize-touched)?  After all, the
only real difference is the predicate used in the mapatoms function.
