Oh right. This accidentally quoted line helped me find out that
etc/default/xencommons is listed in debian/not-installed because it was
not installed before. However, now it is again, but it was not removed
from not-installed, and this solves the mystery of dh_missing not
complaining about it.

It seems useful to me to keep the dh_missing --fail-missing, so the
workaround for the dh-exec bug will now be to also list
etc/bash_completion.d/xl.sh in not-installed, with a short explanation
in a comment.

Now I can do dpkg-buildpackage -A without the error.

(this commit hash will likely disapper again later, but today it'll be
there :) ).
