histedit: byteify the help for the multifold action While there's some allowance for str in `_()`, it's commented to be for "goofy unicode docstrings in test", so no idea how well that works, but it should at least come back as bytes. With HGPLAIN, however, the str isn't touched and is returned as-is, so this seems like a real bug.
