The following alternative version takes the simplistic view that (unless they end the final sentence of the paragraph) '''?''', '''!''' or '''.''' will only end a sentence if they're immediately followed by a space. This of course is nonsense, given the way English is written nowadays, but it's probably an improvement on the first version without the need to search though an inevitably incomplete list of abbreviations.

"hi there, how are you on St.David's day (isn't it a holiday yet?), Mr.Smith? I'd like to present to you (well someone has to win one!) the washing machine 900.1. You have been nominated by Capt.Johnson('?') to win one of these! Just make sure you (or Mrs.Smith) don't break it. By the way, what the heck is an exclamatory question!?"
