This is really old code and performance certainly is not an issue. I 
wouldn't be surprised if the implementation simply predated the addition of 
command line parsers to the stdlib.

In any case, we are happy about all contributions, not only those that 
address our most urgent needs. Your changes clearly make the command line 
parser more readable.

When you're done with it, please open a pull request.
