ok, let's try another issue :

# ps -G " nobody "
  PID  TT  STAT      TIME COMMAND
75483 con- S      0:10.97 /usr/local/sbin/junkbuster configfile
# ps -G ,nobody,
ps: Invalid (zero-length) group name
ps: Invalid (zero-length) group name
# ps -G ,
ps: Invalid (zero-length) group name
ps: Invalid (zero-length) group name

instead of :

# ps -G " nobody "
  PID TT  STAT      TIME COMMAND
75483 co- S      0:10.97 /usr/local/sbin/junkbuster configfile
# ps -G ,nobody,
  PID TT  STAT      TIME COMMAND
75483 co- S      0:10.97 /usr/local/sbin/junkbuster configfile
# ps -G ,
psx: no group name or id specified

why do you make a difference while parsing commas and spaces ?
in other words, ignore empty values (which may be generated by
a shell script, so, don't warn), except if all values are empty.
