lecker lek-ker in "old" German lyrics

[Klaus Föhl]

Hello,

Some German lyrics from before the times of Neue Deutsche Rechtschreibung
feature ck between two syllables. Without Hyphen it is "lecker", with hyphen
it is "lek-ker". Using lec -- ker or lek -- ker ( on purpose not le -- cker)
the hyphen may or may not appear. Is there anything beyond trial and error
to avoid lec-ker or lekker?

Some time ago there was an idea of introducing "lek == ker" for forcing
a hyphen but otherwise no change to formatting compared to "lek -- ker".
Has there happened anything since (I did not find anything in the 2.16 doc)?

Cheers
Klaus
