I like this variant best.  I don't think that writing strings with
lots of escape sequences to an unbuffered port happens often enough to
justify implementing a second buffering mechanism.

When outputting an escaped char, we can additionally assemble the
escape sequence in a fixed size buffer and then output that in one go.

I will make that change myself in the next days, but if anyone beats
me to it...
