Does anyone need sub ensure_single_alleluia() to add alleluia to an empty string?

Laudétur Jesus Christus!

as the title says, I have a simple question: does anyone need sub ensure_single_alleluia() from LanguageTestTools.pm to add alleluia to an empty string?

Why am I asking: currently, sub nocturn from specmatins.pl adds a versicle to the end of each Nocturn. If it has nothing to add, it adds nothing and the double \n\n seems to get sorted out elsewhere. This is correct, as e.g. in Cistercian Ferial Matins, there is no versicle right after the second Nocturn's Antiphon, but after a Capitulum. However, during Paschaltide, function ensure_single_alleluia() adds a single ", allelúia" to en empty string, which creates an artifact.

It can be seen e.g. on "05-10-2025" in Matins.

The simplest solution seems to be to limit the sub ensure_single_alleluia() from LanguageTestTools.pm to a non-empty string, which is simple enough and also quite logical. But before submitting that, I want to ask, if it doesn't disturb someone other's code.

Thanks for an answer, God bless!

Should be safe to do so.

@mbab Any concerns?

No objection. Even some functions as postprocess_ant & postproces_vr check this.

Very good, thank you for confirmation!
