Log:
  When toggling the display using the "m" command to toggle from 'cpu'
  mode to 'io' mode, an artifact remains because the buffer is not
  "finished" with a NULL terminator using sbuf_finish().
  
  An example of this is, when the "m" command is entered, the title line
  will contain COMMANDND instead of COMMAND. This commit fixes this.
