Bug#518966: lintian: check/scripts remove-of-unknown-diversion is bogus

[Norbert Preining <preining@logic.at>]

Package: lintian
Version: 2.2.7
Severity: normal


Our preinst code contains
   dpkg-divert --add --package luatex --rename \
          --divert /usr/bin/texdoc.notluatex /usr/bin/texdoc
   dpkg-divert --add --package luatex --rename \
          --divert /usr/share/man/man1/texdoc.notluatex.1.gz \
          /usr/share/man/man1/texdoc.1.gz

and the postrm code
   dpkg-divert --remove --package luatex --rename \
          --divert /usr/bin/texdoc.notluatex /usr/bin/texdoc
   dpkg-divert --remove --package luatex --rename \
          --divert /usr/share/man/man1/texdoc.notluatex.1.gz \
          /usr/share/man/man1/texdoc.1.gz


And I still get 
E: luatex: remove-of-unknown-diversion usr/bin/texdoc postrm:11
E: luatex: remove-of-unknown-diversion usr/share/man/man1/texdoc.1.gz postrm:14
E: luatex: orphaned-diversion usr/bin/texdoc preinst
E: luatex: orphaned-diversion usr/share/man/man1/texdoc.1.gz preinst

That is bogus, and it was never an error in the last 5-something
revisions and worked.
