[NotifyContext] now cancels the returned context with [context.CancelCauseFunc]
and an error indicating which signal was received.
os/signal: make NotifyContext cancel the context with a cause This is especially useful when combined with the nesting semantics of context.Cause, and with errgroup's use of CancelCauseFunc. For example, with the following code ctx, stop := signal.NotifyContext(context.Background(), os.Interrupt) defer stop() serveGroup, ctx := errgroup.WithContext(ctx) calling context.Cause(ctx) after serveGroup.Wait() will return either "interrupt signal received" (if that happens first) or the error from serveGroup.
