[howto] Kernel hacker's guide to git, updated

Just updated my KHGtG to include the latest goodies available in 
git-core, the Linux kernel standard SCM tool:

Several changes in git-core have made working with git a lot easier, so 
be sure to re-familiarize yourself with the development process.

Comments, corrections, and notes of omission welcome.  This document 
mainly reflects my typical day-to-day git activities, and may not be 
very applicable outside of kernel work.
