You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: not-in-stable.go
    path of file: ./repos/rclone/bin
    
    the code of the file until where you have to start completion: // This shows the commits not yet in the stable branch
package main

import (
	"bytes"
	"flag"
	"fmt"
	"log"
	"os"
	"os/exec"
	"regexp"

	"github.com/coreos/go-semver/semver"
)

// version=$(sed <VERSION -e 's/\.[0-9]+*$//g')
// echo "Checking version ${version}"
// echo
//
// git log --oneline ${version}.0..${version}-stable | cut -c11- | sort > /tmp/in-stable
// git log -
    
func readCommits(from, to string) (logMap map[string]string, logs []string) {
	cmd := exec.Command("git", "log", "--oneline", from+".."+to)
	out, err := cmd.Output()
	if err != nil {
		log.Fatalf("failed to run git log %s: %v", from+".."+to, err)
	}
	logMap = map[string]string{}
	logs = []string{}
	for _, line := range bytes.Split(out, []byte{'\n'}) {
		if len(line) == 0 {
			continue
		}
		match := logRe.FindSubmatch(line)
		if match == nil {
			log.Fatalf("failed to parse line: %q", line)
		}
		var hash, logMessage = string(match[1]), string(match[2])
		logMap[logMessage] = hash
