* src/ls.c (print_dir): Diagnosing the cycle is not enough. Also set exit status to 2. This is what Solaris' /bin/ls does, too. * tests/ls/infloop: Rework test: match both expected stdout and stderr. Require an exit status of 2 in this case. * doc/coreutils.texi (ls invocation): Mention that a loop provokes in an exit status of 2. * NEWS (Bug fixes): Mention it. Reported by Yang Ren in http://bugzilla.redhat.com/525402. * THANKS: Correct ordering of Yang Ren's names.
