this patch cleans up the ps(1) man page some more:

O there's no reason the semantics of the -x flag are being explained in the
  -a flag description

O be more precise regarding the relation between the -a flag and the
  security.bsd.see_other_uids sysctl

O describe the format of the -t flag's argument

O 'con' no longer is a possible entry in the 'TT' column

O explain that the 'TT' column refers to pseudo-terminals via mere numbers

O add a hint in the 'tt' keyword description that a keyword 'tty' exists,
  which will give the full terminal pathname
