Lintian tag information: incorrect-packaging-filename (type: warning)

Description (from lintian-explain-tags)

Some packaging files obtain different names when they are copied from
source to installation packages. Debhelper sometimes adds *.Debian
extensions to NEWS, README and TODO files. That can be confusing.

Debhelper's behavior also depends on the filename.

This source package contains a file that debhelper will not find. The file
will not be included in your installation packages. Important information,
such as incompatibilties on upgrades, may not reach your users.

Please rename the file as indicated.

Please refer to Bug#429510, Bug#946126, and Bug#946041 for details.
