I think the above example forgets "-a" on the final "git commit"
step. With it added, I can understand the concern (and I am sure
you would, too).
The user is trying to add everything done in the working tree, and
"commit -a" would catch all changes to paths that were already
tracked, but a separate "add" is necessary for newly created paths.
But adding a new path means the index no longer matches HEAD, and
the "commit -a" at the final step sweeps the changes to already
tracked paths---failing that because there "already is something
staged" will break the workflow.
