It is protected with quotes ("") in the first place. Why will it get separated
by bash into 3 strings?
In any case, without the outer back-quotes that you put the DAEMON and
ARGUMENTS vars are simply being displayed. And with them I am getting the
previous behavior.

In case it might give someone a hint, here is the main part of powercom.c. The
command line arguments get parsed here.
