I want to do this not by tweaking magic numbers like in the linked answer, but in a way that is robust against spacing changes (like changing paper size or font size or minimum distance between notes or words, or adding manual breaks in the notes, etc.). (The red line is only here for showing the alignment - I don't want such a line in the output.)
I want to align the end of the melisma extender line with the last note of the melisma. I have a melisma defined like so \relative This is a follow-up question to this answer.
