This action says in the documentation that if your docs build from your master branch you should simply set the gh-pages-branch to master to have it make a commit on that branch instead.

However, if you trigger the workflow while you are on the master branch itself, then because the action runs a git fetch <branch>:<branch> the action will fail with error:

/usr/bin/git -c user.name=github-action-benchmark -c user.email=github@users.noreply.github.com -c http.https://github.com/.extraheader= fetch origin master:master
fatal: Refusing to fetch into current branch refs/heads/master of non-bare repository
Error: Command 'git' failed with args '-c user.name=github-action-benchmark -c user.email=github@users.noreply.github.com -c http.https://github.com/.extraheader= fetch origin master:master': fatal: Refusing to fetch into current branch refs/heads/master of non-bare repository

See this workflow for an example.

Possible solutions include adding a field

should-fetch: true|false

to indicate whether the branch needs to be fetched before creating a commit.

Thank you for the awesome action!
