Bug#761649: lintian: could warn about files installed in /usr/share/mime/ other than in packages/

[Yann Dirson <ydirson@free.fr>]

Package: lintian
Version: 2.5.26
Severity: wishlist

The spec in /usr/share/doc/shared-mime-info/ tells that most stuff
under /usr/share/mime/ is a cache generated from
/usr/share/mime/packages/.

This was arguably a design decision that violates the FHS and does not
help anyone to understand what's going on, and when some upstream
packages installs such a file by error, it's not so easy to track the
reason for the resulting piuparts failures (see
http://bugs.debian.org/749582 and http://bugs.debian.org/726799)

A lintian check seems to be a good idea in that case.
