That comes from the ia32-apt-get prior to version 15, which was in
violation of policy by modifying the sources.list directly. Version 15
introduced a new way that leaves all conffiles as they are and only
creates new ones with a clear prefix to avoid name clashes. Updating
from <= 14 undoes the modifications to sources.list by restoring the
original file.

So that is what you are seeing. See
/usr/share/doc/ia32-apt-get/NEWS.Debian.gz for a description of how it
works now.
