It is possible to check the break status of the NonMusicalPaperColumn
to the left of the StanzaNumber. This eliminates the need to filter a
list of all grobs on the line.
First, you need the StanzaNumber's column. Then you can get its left
neighbor (which is needed b/c the stanza's column is a PaperColumn and
won't carry useful break info.). If the neighbor is non-musical and
right-broken, we're at the start of the line.
&=====================
#(define (at-line-beginning? grob)
(let* ((col (ly:item-get-column grob))
(ln (ly:grob-object col 'left-neighbor)))
(not (and (eq? #t (ly:grob-property ln 'non-musical))
(= 1 (ly:item-break-dir ln))))))
#(define (keep-stanza-number-at-line-begin grob)
(if (at-line-beginning? grob)
(ly:grob-suicide! grob)))
&====================
The override to use would be:
%====================
\override StanzaNumber.after-line-breaking =
#keep-stanza-number-at-line-begin
&====================
I don't know how infallible this is :)
Hope this is useful!
