Hi Trevor,
I think I might treat the "m" as a separate lyric event, i.e. as a separate syllable, like this:
Well, that's one way of doing it…
I don't like it, though: it's not the convention (cf. Gould, bottom of pg. 453), nor is it particularly intuitive for a singer.
That being said, you *did* give me a hint which inspired the attached modified snippet, which works (pretty well!) by tweaking the LyricHyphen so that it mimics an extender. Unfortunately, it still requires some manual input with trial-and-error, for the LyricHyphen length — once the current commission pressure is off, I'll see what I can do about somehow making it automagic.
Thanks!
Kieren.
