Re: How to tweak glissandos with a scheme function?

[Papa Eric]

Thanks, it works nicely. And it was in the reference after all, but not 
so clearly:

under spanner-interface:

minimum-length (dimension, in staff space)
    Try to make a spanner at least this long, normally in the 
horizontal direction. This requires an appropriate callback for the 
springs-and-rods property. If added to a Tie, this sets the minimum 
distance between noteheads.

I suggest documenting the "appropriate callback" as being 
#ly:spanner::set-spacing-rods, else I doubt I could have guessed even if 
I had found the entry! (BTW, why is length control not enabled by default?)

I have looked at version 11 documentation since, it is really much 
better for a newbie! Thanks to all for it and the quick answers in this 
list!
