Please make sure we error out on sigs like this. Please add a unittest as well! Thanks!

I'm not convinced this is the right approach. Are there existing sigs that rely on automagically fixing this at parse time? Does Snort accept or reject these sigs?

As of 2.8.6 snort rejects these signatures.
within (3) is smaller than size of pattern
