One practice of using git to have one feature per branch.
Let's say a developer has worked on many small features in many branches. Then he sends one pull request to the central (not controlled by him) for each feature he has developed. While he is waiting for all the features be merged into the central repository, he needs to use all these feature locally.
To do so, he may need to merge the changes in these branches to his local master branch. But this can be tedious when he has many branches.
Is there a way to somehow setup a branch so whenever something is committed to the branch, the changes will also be simultaneously committed to the local master branch? By this way, the develop can avoid having to merge changes from many branches.
