This paragraph doesn’t apply to us, so remove it.

Although useful, we are not there yet, so remove the paragraph.

GitHub support Markdown, and it is pretty popular, so use it here too.

These paragraphs talk about descriptive text not about commit
separation.

The section was reduced to its header, so we make the section into
a normal paragraph

We are talking about commits here now, not just about description.

At the same time make the first occurence of "the commit" to
"each commit" so readers don't get irritated by the wrong
grammatical number.
