Thanks for working on this.  Here are some comments:

* Please use 2 spaces and no tabs for indentation.

* Please extend Tests/RunCMake/CommandLine to cover this or find
  another appropriate test to update.  All options need coverage,
  including the error cases.

* The cmHasLiteralPrefix helper function may be useful in place
  of "x.find(...) == 0".

Thanks,
