PrintErrln & PrintErrf prints to stdout

[bukowa]

PrintErr prints to ErrOrStderr but PrintErrln and PrintErrf prints using Print which prints to OutOrStderr.

cobra/command.go

Lines 1190 to 1193 in 02a0d2f

	// Print is a convenience method to Print to the defined output, fallback to Stderr if not set.
	func (c *Command) Print(i ...interface{}) {
	fmt.Fprint(c.OutOrStderr(), i...)
	}

Lines 1205 to 1218 in 02a0d2f

	// PrintErr is a convenience method to Print to the defined Err output, fallback to Stderr if not set.
	func (c *Command) PrintErr(i ...interface{}) {
	fmt.Fprint(c.ErrOrStderr(), i...)
	}
	// PrintErrln is a convenience method to Println to the defined Err output, fallback to Stderr if not set.
	func (c *Command) PrintErrln(i ...interface{}) {
	c.Print(fmt.Sprintln(i...))
	}
	// PrintErrf is a convenience method to Printf to the defined Err output, fallback to Stderr if not set.
	func (c *Command) PrintErrf(format string, i ...interface{}) {
	c.Print(fmt.Sprintf(format, i...))
	}

Thats how it is now:

// PrintErrln is a convenience method to Print to the defined output, fallback to Stderr if not set. 
// PrintErrf is a convenience method to Print to the defined output, fallback to Stderr if not set.
