Thanks for collecting all these; you're making my life really easy.
One minor point is that the standard format for Fixes: is 12 characters,
not 10.  eg,

Documentation/process/5.Posting.rst:    Fixes: 1f2e3d4c5b6a ("The first line of the commit specified by the first 12 characters of its SHA-1 ID")

I have this in my .gitconfig:

[pretty]
        fixes = Fixes: %h (\"%s\")

and in .git/config,

[core]
        abbrev = 12

I'm working on the commit message now.
