[Q] push refspec with wildcard pushes all matching branches

Dear all,

I'm a little confused, that a push refspec with a wildcard changes the number of branches pushed.

Here is what I see with Git 2.25:

     $ git --version
     git version 2.25.0
     $ git config --list
     user.email=bert.wesarg@googlemail.com
     user.name=Bert Wesarg
     $ git init --bare bare.git
     $ git clone bare.git repo
     Cloning into 'repo'...
     warning: You appear to have cloned an empty repository.
     done.
     $ cd repo
     $ git config push.default current
     $ echo foo >foo
     $ git add foo
     $ git commit -m foo
     [master (root-commit) 4d0b276] foo
      1 file changed, 1 insertion(+)
      create mode 100644 foo
     $ git branch master-two
     $ git push --dry-run
     To ../bare.git
      * [new branch]      master -> master
     $ git config remote.origin.push 'refs/heads/master*:refs/remotes/origin/master*'
     $ git push --dry-run
     To ../bare.git
      * [new branch]      master -> origin/master
      * [new branch]      master-two -> origin/master-two

Is this expected behavior?

Thanks.

Best, Bert
