Subject: [PATCH 2/4] Check empty subdirectory ownership
When checking if a package owns a directory, it is important to check
not only that all the files in the directory are part of the package,
but also if the directory is part of a package. This catches empty
subdirectories during conflict checking for directory to file/symlink
replacements.
