@nwtgck Give me your review.

@peaceiris Thanks.

I also think without---global is better. However, git config still changes the environment of current working directory. So, I think using git commit --author="myname <myemail>" ... is better to minimize the effects.

I tried to use git commit --author and got this problem: https://github.com/peaceiris/actions-gh-pages/runs/501948622?check_suite_focus=true#step:13:94

We can use a local git repository config (.git/config) instead of git commit --author.

This action creates a temporary directory, copies publish_dir/** under the directory, and uses it as a local git repository for each deployment. The following steps will not be broken by this action.

Could you review this change again? @nwtgck

@peaceiris Very great! Now ,I understood git commit --author causes Please tell me who you are. and the actions creates a temporary directory.
