Damien Neil 14491a2ec4 fmt: support %w ... When fmt.Errorf is provided with a %w verb with an error operand, return an error implementing an Unwrap method returning that operand. It is invalid to use %w with other formatting functions, to use %w multiple times in a format string, or to use %w with a non-error operand. When the Errorf format string contains an invalid use of %w, the returned error does not implement Unwrap.
