Feedback

Thanks for the feedback @trasz - I can see the argument for isolation - but shelling out introduces it's own problems. The APIs are implicit + can break without anyone noticing. If the output (API) of fstyp changes it's dependencies could break or exhibit undefined behaviour, and this will not be obvious to the person making those changes. Also consuming fstyp as a library makes it much easier to see it's dependencies, they are declared in the build files.

Ok, after additional feedback from @rgrimes I have reworked the patch. Thanks for the feedback.

I see that doing the validation twice makes no sense. However I do
like the idea of validating inputs early on in the program execution. It's
also where the rest of the command line argument validation exists, so it seems
like the natural place for it?
