{} was never a completly reliable method to suppress a ligature (see
exercise 5.1 in the texbook), and obviously it now fails completly
in luatex due to the changes in the ligature/hyphenation handling
(it doesn't work in context either). 

csquotes should better insert either \/ or \kern0pt before the
ending quote.


f\/i f\kern0pt i fi f{}i

bla!\/` bla!\kern0pt` bla!`
