py3: decode prompt string before calling rawinput Calling input() (aka pycompat.rawinput() on python3) with a byte string displays a byte string in the console. E.g. in interactive commit, we get: b"examine changes to '<file>'?\n(enter ? for help) [Ynesfdaq?]". Similarly, "hg email" prompts are messed up. We thus decode the prompt string before running rawinput().
