From: Colin Ian King <colin.k...@canonical.com>
char array cmd is being scanned in using a %4s scanf format
specifier and so cmd must be an array of 5 chars. Increase size
to 5 chars to ensure we don't have an overflow.
Detected with static analysis by cppcheck:
"(error) Width 4 given in format string (no. 1) is larger than
destination buffer 'cmd[4]', use %3s to prevent overflowing it."
