Bug#913659: Document that not all bugs are policy violations

[Ian Jackson <ijackson@chiark.greenend.org.uk>]

Package: debian-policy
Version: 4.2.1.4

The discussion in #913572 is just another instance of the following
antipattern:

   Submitter:   program X does strange thing Y which is undesirable
   Maintainer:  Y is not against policy

I suggest adding something like this to s1.1, "Scope", as a new 3rd
paragraph:

  This manual cannot and does not prohibit every possible bug or
  undesirable behaviour.  The fact that something is not forbidden by
  Debian policy does not mean that it is not a bug, let alone that it
  is desirable.  Questions not covered by policy should be evaluated
  on their merits.

Ian.
