As mentioned in install.cc I would prefer that "do_not_create_any_shortcuts"
simply result in an early return from CreateOrUpdateShortcuts() instead of
actually enabling the other prefs.

The less coupled preferences are the easier to maintain, i.e.: with this design
if we want to later add do_not_create_start_menu_shortcut we have to make sure
it is enforced here; where as if do_not_create_any_shortcuts only causes an
early return it automatically enforces all the do_not_create_*_shortcut without
explicitly coupling them.

Agreed, done.
