// FormatRecoveredError is used in cases where a panic/recover receives an
// object which is potentially an error that could be wrapped, instead of
// formatted, so that callers can see it.  This may be useful, for example,
// with custom Allocators which panic to signal failure; these panics will be
// recovered as wrapped errors, letting the client distinguish them.
