(I didn't remember that I had sent this patch...). I'll take a look at the function you mention, when I have some time. In any case, keep in mind that there are some conventions in verse numbering: the white lines (separation between stanzas) are never numbered and there is a sequence: 5 (first verse alwais remains unnumbered) ... 10 ... 15 ..., which can be chosen using the :lines attribute. :lines t defaults to a sequence of 5 verses. I chose this syntax to follow the syntax of verse numbering with output to LaTeX (another patch of mine that is already included in Org. In that case, the 'verse' LaTeX package is used). Verse numbering is a special case. In fact, a long time ago I wrote this package: https://gitlab.com/maciaschain/org-verse-num Best regards, Juan Manuel
