  Log:
  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 does not get us to match POSIX/SUSv3, but it gets us closer.  The
  `-g pgidlist', `-R ruserlist' and `-s sidlist' options mentioned in
  freebsd-standards are still under debate, so they skipped for now.
  It should be true that this introduces no user-visible incompatible
  changes, except to support "new stuff" that was not supported before.
