Ok, so I figured it was silly of me to be so lazy as to not even
check to see what my own program does in this case..  :-)

Yes, it does work.  But you have to remember to remove the
"qfwrite" flag (Query First Write) flag in s:brutab for each
of the devices that you wish to write to without confirmation
the first time you try to write to it.  Thus backing up to four
disks, for example, consists of the following:

	(load all four drives)
	bru -c <other options as desired>
	df1:
	df2:
	df3:
	(reload all four drives again)
	df0:
	df1:
	df2:
	df3:
	(reload all four drives again)
	.
	.
	.

Allowing the use of multiple -f options to set up a list of
devices to cycle through is trivial.  Thus the above action
would be reduced to:

	(load all four drives)
	bru -c -f df0: -f df1: -f df2: -f df3: <other options>
	(reload all four drives again and hit RETURN)
	(reload all four drives again and hit RETURN)
	.
	.

I will attempt to get this feature in before the next beta release,
unless I discover some reason why it should not be implemented.

-Fred
