Setting config.replaceNewlines to '\n' not seperating messages in IRC

[petebp]

The proposed setting to config.replaceNewLines to '\n' should split messages in IRC on linebreakes to separate messages in IRC.

But instead of this, the first line is repeated multiple times (number of repetitions seems to be (number of linebreaks)-1).

If you answer another message with linebreaks in Telegram, the answer will not be send to IRC at all, but just the part before the linebreak of the original (quoted) message.
