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().
