It is not at clear to me that an "no archive" bit is such
a good idea.  My main objection is that it is implicit -- if
I set the bit for /usr/rsc, it's hard to see quickly that
/usr/rsc/lib/profile is not archived.  Then again, we already
have this property with walk -- if I chmod 700 /usr/rsc then
even if /usr/rsc/lib/profile is mode 666, no one else can edit it.
Further, if you wondered why "cat `{yesterday lib/profile}" wasn't
working, it would tell you:

	glenda% cat `{yesterday /usr/r/lib/profile}
	cat: can't open /n/dump/2003/0921/usr/r/lib/profile:
		'/n/dump/2003/0921/usr/r' does not exist
	glenda%

or at least it should -- the error-generating code appears
not to be working properly.  It actually says:

	glenda% cat `{yesterday /usr/r/lib/profile}
	cat: can't open /n/dump/2003/0921/usr/r/lib/profile:
		'/n/dump/2003/0921/usr/r/lib/profile' does not exist
	glenda%

which is wrong.
