I played a bit with what we have and in a next upload you can do this:

au{f-}{f}{ff}(f\zwnj f)asse




then is like:

au\discretionary{f-}{-f}{f\zwnj f}asse


Just an experiment. I don't know when there will be an update because 
first WS and I have to test and double check some new stuff as we don't 
want users to suffer too much from a couple of fundamental new features.
