The windows workflow here is broken despite how many times I "retry", it can't checkout the ref... Can someone do a manual rebase?

This is a good start but I think it's incomplete.

• Personally I'd prefer an argument name like password-attempts vs num-tries.
• I'm thinking rnpkeys should also accept and utilize this argument.
• I don't think rnp actually utilizes this, does it?
