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
