As the website includes *examples* of git formatted patches, no change
is necessary.

I've learned through writing those instructions that it is a bad idea to
_add_ additional words, because it gives people _more_ things to argue
about.  One form of words or examples is fine for one group of people,
but completely confuses another group of people.  You can't win.

That is one of the biggest reasons I hate writing user documentation.
