No, I think I was wrong.  This is code from preinst, and it does the
following:

if [ -r $orig ]; then
   ... check md5sums, rm or mv accordingly
else
   if [ -n $version ]; then
      thouch $new.preinst-deleted
   fi
fi

After that, in postinst:

    if [ -f "$cfgfile.preinst-deleted" ]; then
      echo "It looks like $cfgfile has been removed."
      ...

So if this file (preinst-deleted) is there, this means that the file
actually was deleted at the old place.  Ralf said that he didn't purge
tetex-base, and the file wasn't a conffile in tl 2005, anyway.  So
somehow our script's logic is flawed...
