Do these lines above actually need reflowing? Their content hasn't changed 
making it more difficult to spot the significant changes below here.

Does this actually capture the intent of the user confusion it's meant to 
cover? I may have missed the original discussions.

For a clean commit checkout my mental model is not one of anything new being 
actively staged i.e. different from what was in the commit. I can see that 
if a particular tree is checkout then it's implicit staging could well be a 
surprise.

I am in favour of improving the documentation to avoid user surprise
