+Test dune uninstallation of mangpages, and particularly the potential removal
+of the manpages folders such as `<prefix>/man/man1/`, which may, or may not be
+empty (because other tools/projects can install manpages to these directories,
+either before, or after dune installs a project).

+Uninstall the project; since the manpage directory contains pages from other
+tools, dune should not remove it, nor complain about it being non-empty.
