* commit '1b6a32c79ce23995fc87de172af1ea145d5e4853':
  Fix TOYBOX_VERSION
  Basic success/failure return from pgrep/pkill.
  ps: Show [stat2] for any otherwise blank process name field, expand TNAME to 27, use generated constant for stat field parsing loop.
  In cp -a, don't complain if non-root user can't chown, failure is expected.
  Add output path to cp error message filenames.
