Bug#373767: lintian: Add support for --pedantic informational messages

[Jari Aalto <jari.aalto@cante.net>]

Package: lintian
Version: 1.23.21
Severity: wishlist

Currently lintian produces output of:

	W:
	E:

Consider adding a more fine grained level to control program reports
e.g. to add future check that are not neither warnings or errors. These
additional messages:

	N:	(note)
	I:	(info)

Could be used for anything that is not absolutely necessary, but
which would improve quality and maintenance. The NOTE category
would be above INFO category, suggesting that those practises should
be highly encouraged. These messages could be enable using additional
options in lintian:

  --pedantic		(enable everything)
  --enable info		(enable specific level)
  --enable note		.. 

As lintian is written in Perl and uses I assume linti, the additional
options would be easily added.

EXAMPLES:

- "known best practices" gathered from known tips:
   * e.g. of there is one huge patch, the message could be

   note-should-use-patch-control

   And lintian-info would suggest person to invest arranring
   his patches to use dpatch(1) or quilt(1) etc. other standard
   tools.

- "missing watch file"

   note-missing-upstream-watch-file

   And lintian-info would suggest person to use debian/watch
   to track the upstream sources
