Synopsis:
   set exec_protection [on|off|toggle]

Description:
   If turned on, this setting will disable use of the EXEC command from
   within hooks.  This is a security feature intended to prevent malicious
   users from tricking new users into setting hooks containing backdoors,
   whether by typing them in by hand, or by loading them from premade
   scripts.
