Steps to reproduce:
1. Connect to any network
2. Switch to any channel or query buffer
3. Type in any message with a length greater than 512 characters
4. Press ENTER to send the message
Expected result:
The sent messages are echoed, the prompt is cleared and then redisplayed.
Observed result:
See attached screenshot. The overflow/split marker bleeds over into the
prompt area (in the area just before the nick) after the messages are
echoed.
The superfluous red background persists until an edit action or motion
is performed.
Patch / Fix:
The patch resets the color pair for the input area in inputUpdate().
