All 6 of March's SanctiM-track saints authored. St. Benedict's own
patronal feast turns out to be the richest case in this pass so far:
its Nocturn 3 is genuinely Monastic-only content (a St. Peter Damian
sermon) absent from the Tridentine track entirely, unlike every other
saint done so far where the SanctiM file just reslices the same
Tridentine text. Also caught a case (St. Gregory the Great) where a
saint's SanctiM file carries content copied verbatim from an unrelated
feast rather than anything proper to the saint himself.
