Log:
  MFC 225908, 225912, 225927:
  
  225908:
  - Reorder default ps(1) output according to reality.
  
  225912:
  - there's no reason the semantics of the -x flag are being explained in
    the -a flag description
  - be more precise regarding the relation between the -a flag and the
    security.bsd.see_other_uids sysctl
  - describe the format of the -t flag's argument
  - 'con' no longer is a possible entry in the 'TT' column
  - explain that the 'TT' column refers to pseudo-terminals
    via mere numbers
  - add a hint in the 'tt' keyword description that a
    keyword 'tty' exists, which will give the full terminal pathname
  
  225859:
  - Correct a typo that was introduced in 225912
