* commit 'e0f2d3d3e0f5815582a2d9a328cf2f94cf8172ec':
  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.
