-/* Maximum line length - split to two lines if it's longer than this.
-
-   This is mostly to prevent excessive memory usage. Like if someone DCC
-   chats you, you both have very fast connections and the other side sends
-   you 100 megs of text without any line feeds -> irssi will (try to)
-   allocate 128M of memory for the line and will eventually crash when it
-   can't allocate any more memory. If the line is split at every 64k the
-   text buffer will free the old lines and the memory usage never gets
-   too high. */
