I think this makes it slightly clearer that the presence of relevant
license or DFSG requirements is (only) a necessary condition for using
the field.

New text from Russ Allbery <rra@debian.org> in #944325.

* Add missing close brackets to the examples in the Diversions
  appendix.  Thanks, Abou Al Montacir.

* Remove mention of the old Packaging Manual from the package
  description.  This is ancient history and no longer likely to be
  helpful.  Thanks, Holger Levsen.  (Closes: #941835)

Mostly from Sean Whitton.  Also revert some unrelated informative
changes, leaving only clarity and formatting fixes.  Drop the
sample minimal debian/rules file, leaving only a reference to the
dh documentation.  Don't stress a new packaging helper to make it
more obvious that cdbs is one of the expected exceptions to this
advice.
