Same problem with soffice.sh and psprint.conf ...

I have now added a workaround for these problems in piuparts, deleting
/etc/openoffice/{sofficerc,soffice.sh,psprint.conf} if their
/etc/libreoffice/* counterparts exist before performing the upgrade from
wheezy to jessie (at this point nothing "bad" has happened, yet).

The solution for cleaning this up in stretch would be in
libreoffice-common.preinst:

  for conffile in /etc/libreoffice/{sofficerc,soffice.sh,psprint.conf}
    if md5sum(conffile) == known_md5sum_squeeze(conffile)
      restore conffile from embedded copy from jessie
    fi
  done

Not sure if someone wants to implement this (I don't :-P) ... but IIRC
one package actually did recovery this way (for a single conffile), but
I don't remember who implemented it.

We could reconsider this option if it seems to be easier than dealing
with the bug reports being filed after stretch got released :-)

Anyway, we should keep this bug report open (and wontfix) as
documentation for people running into it.
