New Revision: 270245
URL: http://svnweb.freebsd.org/changeset/base/270245

Log:
  MFC r262872: fts: Don't abort if an empty pathname is given.
  
  Make fts_open(3) treat an empty pathname like any other pathname that cannot
  be lstatted because of [ENOENT].
  
  It is rather confusing if  rm -rf file1 "" file2  does not remove file1 and
  file2.
