commit 6f29842913fb722f8b12e1361a018679874d6d0e
from: Omar Polo <op@omarpolo.com>
date: Sun Sep 20 21:40:45 2020 UTC

rework a bit the subtitle line

the `by` field of `music` is optional, and while there simplify the
code.  Use only a single final "." both for when there is a music and
when there's not
