Bug#663447: lintian: False positive: executable-debhelper-file-without-being-executable

[Felix Geyer]

Package: lintian
Version: 2.5.5
Severity: normal
Tags: patch

Lintian emits the executable-debhelper-file-without-being-executable tag for 
directories.
For example sdl-image1.2 has a directory called debian/examples.

Attaching a patch that adds a check so the tag is only emitted for real files.
