I agree with mkeash's comment. Isn't this also the whole point of the staging area? "Stage multiple fixes into a single coherent commit," is the underlying model. Instead, in the above example there are many granular commits, with rebasing used to then clump them into a logical grouping.

This would indicate to me that you are committing too often or not using the staging area properly.

Committing often allows you to remember the small changes you made throughout the feature. If you let a file sit in the staging area for hours, days, weeks, you will most likely have a hard time remembering why you made all the changes.

Is there a way to do this with the staging area? o.O

Merge commits, particularly those that merged master multiple times effectively destroy history (by preserving it). For that matter, many projects maintain all commits to master should work! Unless you advocate only committing entirely working states (unlikely for large features), you'd have to rebase.

Can you explain what you mean by effectively destroying history by preserving it? That doesn't make any sense to me. And I also don't understand the link between merge commits and a failure to ensure that all commits to master should work. If you make changes in a branch, get everything up and running there, then merge to master, does that not ensure that everything on master works?
