(compare-windows-highlight): Add new value
`persistent' and change :type from `boolean' to `choice'.
(compare-windows-overlays1, compare-windows-overlays2):
New internal variables.
(compare-windows-highlight): If compare-windows-highlight is
`persistent', add current overlays to compare-windows-overlays[12]
instead of adding compare-windows-dehighlight to pre-command-hook.
(compare-windows-dehighlight): Delete all overlays from
compare-windows-overlays[12].
