[issue3982] support .format for bytes

[Martin v. Löwis]

Ah, right. So I would still use

   '{0:x}'.format(100).encode("ascii")

rather than the format builtin format function. Actually, I would
probably use

  ('%x' % len(bytes)).encode("ascii")

This I don't understand. What porting becomes more difficult?
>From 2.x to 3.x? Why do you have any .format calls in your code that you
want to port - .format was only added in 2.6, so if you want to support
2.x, you surely are not using .format, are you?
