dcrochu as of 22/01/2024, changed one ql!cl- to ql!cl because the syllable is weak (cf. also the ms in which this neume is on doMInus). Added rsign, typographical standardization.

ql!cl- was added back, cf the discussion of this in https://github.com/Nocturnale-Romanum/nocturnale-romanum/issues/21
