New Revision: 226192
MFC 225908, 225912, 225927:
- Reorder default ps(1) output according to reality.
- 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
- 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
- Correct a typo that was introduced in 225912
