Author: jilles Date: Sun May 9 19:30:52 2010 New Revision: 207826 URL: http://svn.freebsd.org/changeset/base/207826 Log: MFC r207483: pathchk: Add the new POSIX -P option. This option checks for empty pathnames and components starting with '-'. Our -p option also checks for the latter, which remains the case.
