How would you turn this:
Dear Fred How are you? Regards John
Into this:
Dear Fred How are you? Regards John
Note: Single and double breaks are allowed, but no more than that. For example, we want to go from:
"Dear Fred\n\n\n\nHow are you?\n\n\n\n\n\n\nRegards\nJohn"to
"Dear Fred\n\nHow are you?\n\nRegards\nJohn"
But should also work for "\r\n".
