Hello rsc (cc: golang-dev@googlegroups.com),

I'd like you to review this change.

LGTM

I wonder if there should be a %#U format that prints one of

U+%04x
U+%04x (%c)

depending on whether the argument is printable.
The errors that say (%c) U+%04x now will look bad
if %c is say '\n'.

perhaps. it's easy but of course that issue is why the character is
printed twice in those errors.
