patch, 8 partsSmall documentation updates

This, my first patch series, adds small documentation updates covering points I had noticed or had to research elsewhere.

The small 'git' update applies on top of Junio's changes in 'next'. e.g. http://article.gmane.org/gmane.comp.version-control.git/204794
