I don't think that's a valid descriptor.

I got an error which points here: UnboundLocalError: local variable 'path_suffix' referenced before assignment
path_suffix won't be set if the else branch above is taken.

This needs to be a return statement.

I think we need to add a linter to Travis :-) Though I guess it's hard to tell because Python doesn't enforce return values.

a71658c displayaddress: descriptor support, make --path a named argument (Sjors Provoost) 163f926 Add descriptor class (Sjors Provoost) 6fc1524 HardwareWalletClient: store fingerprint (Sjors Provoost) Pull request description: Adds a `Descriptor` class, which currently handles some of the descriptor functionality. Changes `displayaddress` to allow a descriptor argument. This means `--path` and `--desc` are now named arguments. When using a descriptor `displayaddress` performs additional checks to make sure the fingerprint and xpub match. To enable the fingerprint check, I'm storing the fingerprint on `HardwareWalletClient` instances.
