I don't think I agree. It would instill good will if git could detect what appeared to be a private key in your code when doing a `git push` and warned you "This file appears to contain a private key, are you sure you want to push this commit? (y/n)" but the responsibility of maintaining security of their keys ultimately lies with the user using those keys. Otherwise you're putting github in a scenario for fault that doesn't originate with them and that's rather unfair IMO.
