[X] Case conversion overlooks leading punctuation


#1

e.g. default Sentence and Mixed case do

¡misterio! -> ¡misterio!, not ¡Misterio! as expected

Workaround: add all punctuation chars to 'Words begin from/after any of:'.


#2

Till now this has been intended behaviour.

Maybe it is more convenient to add these characters by default.
