Gregofacsimil, with a correction on SUper: added missing note, natural Si, following (F-Pn) lat. 12.044 et al. Neumes from H + rsigns according to H. Verse from H.

Reverted natural si to flat si, per dcrochu's advice.

Backported dcrochu's corrections

I disagree with dcrochu on Gelboë(ghf|toM1) in the verse. H has an ordinary to.
