Make git push options accept short name

[wxiaoguang]

Just like what most CLI parsers do: --opt means opt=true

Then users could use -o force-push as -o force-push=true

why not using len of push options?

But why using len of push options?

But why using len of push options?

I think it's better set a length when we know the max length of a slice.

But there could be far more push options than it really needs here.

At most, here it only needs 2, but there could be 4 or 5 or even more push options. They are not related.

LGTM. by the way, suggest add this test function also.

func TestAgitPullPush(t *testing.T) {
	onGiteaRun(t, func(t *testing.T, u *url.URL) {
		baseAPITestContext := NewAPITestContext(t, "user2", "repo1", auth_model.AccessTokenScopeWriteRepository, auth_model.AccessTokenScopeWriteUser)

		u.Path = baseAPITestContext.GitPath()
		u.User = url.UserPassword("user2", userPassword)

		dstPath := t.TempDir()
		doGitClone(dstPath, u)(t)

		gitRepo, err := git.OpenRepository(context.Background(), dstPath)
		assert.NoError(t, err)
		defer gitRepo.Close()

		doGitCreateBranch(dstPath, "test-topic")

		// commit 1
		_, err = generateCommitWithNewData(littleSize, dstPath, "user2@example.com", "User Two", "branch-data-file-")
		assert.NoError(t, err)

		// push to create a agit pull request
		err = git.NewCommand(git.DefaultContext, "push", "origin", "HEAD:refs/for/master/test-topic").Run(&git.RunOpts{Dir: dstPath})
		assert.NoError(t, err)

		// check pull request exist
		unittest.AssertExistsAndLoadBean(t, &issues.PullRequest{BaseRepoID: 1, Flow: issues.PullRequestFlowAGit, HeadBranch: "user2/test-topic"})

		err = git.NewCommand(git.DefaultContext, "reset", "--hard", "HEAD~1").Run(&git.RunOpts{Dir: dstPath})
		assert.NoError(t, err)

		// test force push without confirm
		stderr := strings.Builder{}
		err = git.NewCommand(git.DefaultContext, "push", "origin", "HEAD:refs/for/master/test-topic").Run(&git.RunOpts{Dir: dstPath, Stderr: &stderr})
		assert.Error(t, err)

Great, thank you for the awesome test.
