Spinner overwrites the previous line if it is not ended with "\n"

[medyagh]

Hello a few years ago we created this issue #121 and this PR #108

and we been using a fork of spinner for the issue that we have, however I would love to use the main repo,
admittedly at that time we didnt explain the issue Outside minikube context and here is my second attempt hopefully this time makes better sense :)

here is a simple code using the spanner

package main

import (
	"fmt"
	"os"
	"time"

	"github.com/briandowns/spinner"
)

func main() {
	_, err := fmt.Fprintf(os.Stdout, "Hello time world is %d:%d", 3, 4)
	if err != nil {
		fmt.Println("Error !")
	}
	s := spinner.New(spinner.CharSets[9], 100*time.Millisecond)
	s.Color("green")                                            
	s.Start()                   
	time.Sleep(4 * time.Second)
	s.Stop()                   

}

Output

(spinning without any text)

The Expected Output

Hello world time is 3:4 (Spinning)

Note that the spinner library is Overwriting the Hello...text, since it did NOT end with a "\n"

I also tried the Prefix

	s.Prefix = fmt.Sprintf("Hello world time is %d:%d", 3, 4)

,But whole text will vanish after the spinning is done. we want the "Hello world" text to stay after the spinning.

We also are experiencing this. It seems that if there are a lot of logs in a short period of time, the last one will be consumed. If there is 1 log at a about 1 log per second, the log will never appear and will just be consumed by a brand new spinner message.

In both cases, logs are being buried, with various effect depending on the frequency of the logs

I'll have a look again this week.
