counting clefs in additional bottom/top spaces

[eroux]

Working on #883, I realize it never occured to me that clefs on the first and fourth line should have the same effect on additional bottom/top space as c and k. Not an emergency though...

[eroux]

Oh, virgula and divisio minima should be counted like that too, this would allow much more precise settings

[henryso]

Virgula and divisio minima are on the top line, so shouldn't they count as a punctum on the top line, on j rather than k (for a 4-line staff)? If that's the case, they shouldn't really change the additional top space, correct?

[eroux]

absolutely yes

[henryso]

@eroux Can you give me some samples where a clef on line 1 or 4 should alter something, so that I can see if what I am doing is having any real effect?

[eroux]

I think you can take an example similar to the one in #960

[henryso]

Thanks. That opens one question (in my head). Does the clef at the beginning of the line affect these spaces or only clefs within a line?

[eroux]

Hmmm, I don't think a clef at the beginning of line should be treated differently...
