That applies only for a single branch. If I prepared a couple of
branches for pushing and somehow want to double check what I prepared,
'git push --dry-run' would be quite handy. I know how to handle the
situation and could write a custom script that does all necessary
checks. But I haven't found an out-of-the-box solution for double
checking right before 'git push'
