Similar to the chgrp(1)-audit: 1) Refactor manpage so it's actually fun to read 2) BUGFIX: Call (l)chown properly when the H-flag is specified (only when depth > 0) 3) BUGFIX: Call (l)chown properly when the h-flag is specified (only when depth = 0). 4) BUGFIX: Only recurse() in chgrp() when the initial chownf() succeeds. 5) Style fixes, argv-basing. 6) Rename status to ret for consistency. 7) Add blank line before return.
