Sorry if I wasn't clear. The whole test for am/pm (line 98 - 118) can simply be:
testMap(US, AM_PM, ALL_STYLES,
"AM", "PM",
RESET_INDEX,
"a", "p");
Since we now know that day periods strings won't be leaked into display names,
then the map simply should contain only 4 entries (`AM`, `PM`, `a`, and `p`).
