Ottava clef "8" shouldn't be counted

[Bertalan Fodor]

I think the "8" symbol in an ottava clef (G_8) shouldn't be counted when
calculating staff extent, because lyrics will be to low in that case.

(Now Lily thinks that there will be some collision or too small space below
the staff but that's not true, because there is nothing under the "8"
symbol, so the lyrics could be in one line with that.)

Greetings,

Bert
