When sending text chats from the console, the server is appending a \n to the end of the chat. Before echoing the message on the client side, the client also appends a \n. The result is wasted space and an unnecessarily flooded chat window. Formatting (by appending a mandatory \n) should be done on the client side. The following diff removes the \n being sent from the server side:

slipgate:~/svn/ioquake3/code/server# diff sv_ccmds.c sv_ccmds.c.orig
969c969
<       SV_SendServerCommand(NULL, "chat \"%s\"", text);
---
>       SV_SendServerCommand(NULL, "chat \"%s\n\"", text);
