Live-verified (Monastic Tridentinum 1617) that an Ember day's Lauds
psalmody stays on the plain ferial default throughout -- only the
Benedictus antiphon (and, Wednesday/Friday only, the Magnificat
antiphon) is genuinely proper to the day. Adds the 6 Benedictus +
4 Magnificat antiphon files (Ember Saturday's Second Vespers is
always ceded to the following Sunday on both quarters, so no
Magnificat content exists to author there).
