I obviously agree with this.  As I said a few times I regret
introducing "add -i" --- it encourages a wrong workflow, in that
what you commit in steps never match what you had in the working
tree and could have tested until the very end.
  

On the other hand, not all changes require any testing at all. For 
example, if you're using git to manage documentation, it is totally 
reasonable to commit a fix for a simple spelling error in one part of a 
file while not committing an in-progress rewrite of another part.
