From 44e9fdd0e848382337edb97d41e7317638a67bac Mon Sep 17 00:00:00 2001
From: Allan McRae <allan@archlinux.org>

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.
