Why is there no splitBy in the list module?

fine (if also splitWithPS is changed to splitByPS)

The other versions (not ignoring a final delimiter and deleting all
empty lists) are desirable, too. Are there any suggestions for canonical
names? The implementations could be hidden (and more efficient) then (by
avoiding to traverse a list twice).

How about this?

splitFields, splitWords, splitLines (= split ?)
splitFieldsBy, splitWordsBy, splitLinesBy (= splitBy ?)

splitFields 'a' "baaba" -> ["b", "", "b", ""]
splitLines  'a' "baaba" -> ["b", "", "b"]
splitWords  'a' "baaba" -> ["b", "b"]
