I understand, and agree that ByteStrings are more appropriate. I'm not
particularly attached to Strings. It might nonetheless make sense to
keep the String versions around for the convenience of people who
happen to have gotten a String from somewhere (there are, after all,
quite a few such places), and wish to output it to a file descriptor.
