  Log:
  MFC *:  Support more POSIX/SUSv3 options:
  
    - Change `-p' to allow a list of process IDs, and `-t' to allow a list
      of terminal names, instead of only a single value for each.
    - Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
    - Add the `-G gidlist' (group id).
    - Allow any of these "selector options" to be specified multiple times,
      and have `ps' keep adding to a given list -- instead of replacing the
      previously-specified values.
    - Fix interactions between selector-options, so that: "If any are
      specified, ... ps shall select the processes represented by the
      inclusive OR of all the selection-criteria options." (from SUSv3)
    - Add a `-X' option, which is the reverse of the `-x' option.
    - various minor improvements in parsing and error handling.
  
  This should result in no user-visible changes, except for adding the
  new features.  The man page is updated to describe the new features,
  and to describe the sorting options in better and more complete detail.
