Update tutorial for simplified "git" script.

Use "git commit" instead of "git-commit-script", and talk about using
"git log" before introducing the more complex "git-whatchanged".

In short, try to make it feel a bit more normal to those poor souls
using CVS.

Do some whitspace edits too, to make the side notes stand out a bit
more.
