- git: simplify commit message extraction command
Instead of using "git log <commit>^!", which means "perform a walk
that includes <commit> and excludes its parents", perform a
non-walking command.
We could use "git log --no-walk <commit>" for this. Instead, let's
use the lower-level "git diff-tree", to get into the habit of using
plumbing commands that try to support scripting by behaving simply and
predictably.
Noticed by code inspection.
