Bug#666726: debian-policy: Clarify if empty control fields are ollowed or not

[Andreas Noteng <andreas@noteng.no>]

Package: debian-policy
Severity: minor

The policy does not clearly state if empty control fields in debian/control are
allowed or not. dpkg accepts te use of empty fields, apt does not.
IMHO empty control fields are bad practice, and should explicitly not be allowed.

This bug is of relevance to checkinstall bug #666262
