Okay, here is a little handy regex that I found/created to gather full sentences that are broken over several lines.
/^[A-Z]\_.*?\./
Which translates into:
^ Start the the beginning of a line
[A-Z] Match a capital letter
\_. Match everything including new lines. I got this tip from the link below. Thanks!
* No match or more
? Non greedy! Otherwise the match keeps going until the last line
\. Match the period.
Simple, isn't? :P
