Review Comment:
I think this method could be the default toString on BytesRef, actually...
in most cases when you wish to dump it using toString it's for debugging
purposes: an array of bytes would always be there, utf8 as an additional
helpful hint... why add another method? Even the fact that this additional
method exists points at the need to actually dump BytesRef in a more verbose
way...
