so, it works with any number of files/commands.

while I wholly support managing a network this way, in fact suggest that
it is the only acceptable way, rancid (or some backup system) still plays
a role - for any device whose config can be changed locally (during test,
debug, ???).  it is useful to catch those events.  also configuration is
not the only thing that rancid collects.
