Bug#663516: lintian: Should we retire old/reundant tags

[Niels Thykier <niels@thykier.net>]

Package: lintian
Version: 2.5.5

Hi

I am considering to retire a number of old tags I suspect are now useless.

The following tags are no longer emitted by any package in the entire
archive and I suspect no packager will trigger them.

 use-of-compat-symlink
 postinst-should-not-set-usr-doc-link
 package-uses-obsolete-file
 old-style-example-dir
 old-style-copyright-file [AR]
 obsolete-field
 loads-obsolete-confmodule
 binary-nmu-uses-old-version-style
 ancient-dpkg-predepends-check
 ancient-dpkg-long-filenames-check
 doc-base-file-references-usr-doc


Note: "old-style-copyright-file" is an auto-reject tag, but I see little
merit in keeping it.  Any package emitting said tag will end up emitting
"no-copyright-file" instead.

Furthermore, I am considering to drop the following tags:
 x11-games-should-be-in-usr-games
 manpage-for-non-x11-binary-in-wrong-directory
 manpage-for-x11-binary-in-wrong-directory
 package-installs-font-to-usr-x11r6
 package-installs-file-to-usr-x11r6-bin
 old-app-defaults-directory

Any package triggering any of those tags would (as far as I can tell)
also trigger package-installs-file-to-usr-x11r6.

So, do anyone believe any of these tags are still useful or could
prevent an issue later?  If not, I will remove them.
