Hi,
trying to define an overwrite to draw a circle around a stem I came
up with the code below. Unfortunately it doesn't automagically work
for all use cases as can be seen in the attached image: The code
doesn't take the number of flags into account. I know that the stem
length can be altered with a tweak, but I'd prefer this to be
corrected without manual intervention. Is there a way within the
damp-stem function to force a minimum stem-length depending on the
number of flags if notes aren't beamed?
