Fixed: "Show AM / PM" now hides the marker everywhere rather than only on the
screen that shows the time and nothing else. Three of the layouts never asked
the switch, so with the date or a calendar on screen the marker stayed however
it was set. Wherever it is off now, nothing is drawn and no room is kept: the
time takes the space back. Your existing answer is carried over.

Changed: the switch has moved to where it belongs — inside the twelve-hour
clock's own box in the general settings, above the choices about what the marker
should say.
