Apt-get wants to install "initscripts'

[David <dbree@duo-county.com>]

I'm running a woody system, with testing and unstable included in 
sources.list.  Now, I get the following:

dlb@localhost:~$ su -c 'apt-get -s dist-upgrade'
Reading Package Lists... Done

Inst initscripts (2.85-3 Debian:unstable)
Conf initscripts (2.85-3 Debian:unstable)

dlb@localhost:~$ apt-cache show initscripts

And my apt preferences file:

Package: *
Pin: release a=stable
Pin-Priority: 900

Package: *
Pin: release a=testing
Pin-Priority: 200

Package: *
Pin: release a=unstable
Pin-Priority: 90

Can someone tell me why it's wanting to install this unstable package?   It 
doesn't appear that my system should cause this to happen.  Is this a 
glitch in the dependency list?  I notice that in the "apt-cache show" 
above, it says:
Replaces: sysvinit (<< 2.85-1),
which I have, but the sysvinit I have is stable..

What can I do to stop it from wanting to do this, other than removing 
unstable from my apt list?
