Specifying ':' to suppress the error messages printed by getopt().
Then, distinguish the two types of errors.

Before:
  # virsh -c
    virsh: option requires an argument -- 'c'
    error: unsupported option '-?'. See --help.

After:
  # virsh -c
    error: option '-c' requires an argument

  # virsh -x
    error: unsupported option '-x'. See --help.
ACK.


   Thanks and pushed
