Earlier, 47afed5 (SubmittingPatches: itemize and reflect upon well written changes, 2009-04-28) added a discussion on the contents of the commit log message, but the last part of the new paragraph didn't make much sense. Reword it slightly to make it more readable. Update the "quicklist" to clarify what we mean by "motivation" and "contrast". Also mildly discourage external references.
