Although many people disregard the preciousness of commits and treat them as
save points, they have great value when used correctly. Commits are not just a
better way to save a file. When used right, they are documentation about the
history of the changes. If we treat them as linear save points in our work, the
history becomes extremely noisy with a lot of commits that are "oops, fix
tests", "oops, fix indentation", "oops, fix typo" (referred to oops commits from
here on). Committing stuff that is wrong is inevitable but git allows us to
rewrite the history so that reading it becomes a pleasure and a lot more
efficient.
