[rancid] ! character added to start of GetSystem lines

[Gavin McCullagh]

Hi,

using fnrancid (for fortinet), I've noticed that the scripts prefix lines
from the GetSystem command with a !.

Is this a rancid-specific notation or is this an effort to make these lines
into comments, so the whole file could be loaded up on a Fortinet unit?  As
far as I can see # is the comment character on Fortinet.
