Interesting question that came up at my workplace, too.

Here is what I suggested:
1. Keep working on a single branch and make commits for all features
2. If you make a commit, prefix the commit message with the feature name
3. After you are done with a feature create a new feature branch based on
   your combined feature branch. Use `git rebase -i` [1] to remove all
   commits that are not relevant for the feature. Alternatively you could
   cherry pick the relevant commits [2] if this is faster.

I wonder what others think about this solution. Maybe there is a better
solution that I overlooked?
