.Pp
pathchk(1): Fix the example so it allows arbitrary pathnames. Spaces and various other characters in pathnames are not passed through literally by xargs in its default mode. Instead, use find . -exec ... {} + Although the -- argument is not strictly required here, add it anyway to avoid surprises when modifying the code to find -f -somedir ... MFC after: 1 week
