I have very little time (packing our flat's contents in boxes...), just
two things:

- With the change you suggest, the teTeX version of xdvi.cfg would be
  ignored completely?

- I think it is hardly possible to properly handle all possible
  combinations of changed xdvi.cfg.  What about the following approach:

  * check whether the teTeX file exists, if not just handle texlive
    (ignoring teTeX deletions)
  * if both the teTeX file and the TeXLive file exist, ignore the teTeX
    file 

  * NEWS.Debian in explaining what's happened

Regards, Frank
