Subject: [PATCH] Update interface.c to avoid error messages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When hitting enter (without writing anything) in an chat prompt always appears an error message telling you that the message is empty.
Checking the content of the line can avoid this.
I don't know is this behaviour is wrong or right.
So please forgive me if it doesn’t make sense.
