All reports of file-name-ends-in-whitespace for the archive. The extended description of this tag is:
This package installs a file or directory whose name ends in whitespace. This might be intentional but it's normally a mistake. If it is intentional, add a Lintian override.
One possible cause is using debhelper 5.0.57 or earlier to install a doc-base file with a Document field that ends in whitespace.
This tag has not been emitted in any package tested by Lintian.
