174 Annahmen:
175 - die Routine wird wortweise aufgerufen, mit einem \n am Ende des Strings
176 - Zeilenumbrüche innerhalb des Wortes sind als hyphen/soft hyphen plus space markiert
177
178 TO DO:
179
180 IT: all these rules are taken from Arboreal; do we need them all?
181 IT: richtig? vollständig?
182 IT: Sind die u/v-Regeln wirklich genau wie in LA ? insbesondere: gleiche Vokal-Klasse?
183 IT: Änderungen in den lateinischen u/v-Regeln übernehmen?
184 IT: italienische Beispielwörter für die u/v-Regeln angeben
185 IT: Brauchen wir die Gravis-Regeln aus Arboreal in DICT wirklich?
186 IT: wenn ja: gehört À --> Á etc. in die Wörterbuch-Schicht? Und einschränken auf letzte Silbe?
187 IT: ist prefixCons = (inter | per | ſuper | ſer) auch für Italienisch gültig?
