Most of those abbreviations begin with a capital letter and are only <= 4
letters long. While a sentence certainly may end in something like "Bob."
that may be an acceptable overkill. Then you need to look out for "e.g.",
"i.e.", "viz." and a few more which I can't remember off the top of my
head. That should be possible with lookbehind, something like (untested
since I'm AFC)
s#\v%(%(%(\u\l{1,3}|i\.e|e\.g|viz)\.?)@<![.?!]\)?)@<=#\r\r#g
