Great. Thanks a ton. The problem I was having was that I was using
getline to read from stdin, which stripped the newlines (duh). Changing
it to while(!cin.eof()) input.append(1, cin.get()); fixed it.
By the way, do you have a better way of reading the entire stream,
including newlines, into a string?
