Well, it's not that complicated. Ligatures in German must not happen
at compound break points, while they can be applied to ordinary break
points.
Consider the word `Dorfladen' (village shop). Using `=' to indicate a
compound break point and `-' for normal ones, the proper break points
are `Dorf=la-den' which means no `fl' ligature. Note that `Fladen'
means `cow dung', so having a ligature there is really bad.
On the other hand, consider `Löffel' (spoon). Inspite of the
hyphenation `Löf-fel', a ligature looks good.
