Documentation/submitting-patches: Extend commit message layout description
Add more blurb about the level of detail that should be contained in a
patch's commit message. Extend and make more explicit what text should
be added under the --- line. Extend examples and split into more easily
palatable paragraphs.
This has been partially carved out from a tip subsystem handbook
