cli: cmd history echoes the last command string word twice with --mode=script

PROBLEM:

When a gluster command is executed with --mode=script option
enabled, the last word in the command string is echoed twice
in command history.

  Example:
  [2012-12-03 05:29:16.083176]  : volume start dis dis : SUCCESS

FIX:

Terminate argv with NULL when the words are shifted after omitting
"--mode=script" from it.
