The version of aribas in squeeze does not depend on emacsen-common,
the one in lenny does. Both of these versions install fine, however
when upgrading a lenny system (wihout any emacsen installed) to 
squeeze we get the following:

Preparing to replace aribas 1.63-2 (using .../aribas_1.64-3_amd64.deb) ...
  ERROR: emacsen-common being used before being configured.
  ERROR: This is likely a bug in the aribas package, which needs to
  ERROR: add one of the appropriate dependencies.
  ERROR: See /usr/share/doc/emacsen-common/debian-emacs-policy.gz
  ERROR: for details.
  dpkg: warning: subprocess old pre-removal script returned error exit status 
2

Now this might be due to some overly eager check of dpkg. I didn't try to
investigate this; the change in aribas_1.64-4 fixes this for the squeeze
release without having to touch dpkg. As soon as we do not have to care
anymore for that particular upgrade path we can turn the Pre-Depends back
to Depends.

OK? -Ralf.
