specify the router you want to diff on

Thanks for that start

We are currently doing immediate diffs when the user makes the change
and syslog notices the exit from config mode.  That way the user that
made the change and the managers know when and what the person just did.
We don't do hourly/daily diffs.  So some way to pass (do-diffs -r
"some-router") and have that pass that info along to the control_rancid
and allow control_rancid to do all its normal housekeeping would be the
best way.

control_rancid will also need to be modified.  i'd suggest that a better
way to acheive this would be; given username and router

	% cd /sometmpdir
	% touch router.lock
	% type = `grep ^fqdn /usr/local/rancid/*/router.db | awk -F:
'print $2'`
	% bin/rancid-fe fqdn:<type>
	% diff -c /usr/local/rancid/<group>/configs/fqdn fqdn >
fqdn.diff
	% ucbmail -s "diffs" username < fqdn.diff

or something to that effect, with error detection.  the point is, do it
outside of rancid.  this way the group still gets the diffs when the
hourly (or however often you run) diffs are run.
