GIT "relate" ALIAS to quickly show how all branches relate to HEAD (or given branch). GIT "graph" ALIAS to show the graph between two commits (from HEAD to it origin, or given branch, by default). `graph` Improved to highlight starting point (which is not always obvious).

The "quick" (but perhaps misleading) interpretation of following is:
"you have to go 15 commits backward and then 33 commits forward
to go from HEAD to debian/master
both have 7 (=14/2) commits in common (cherry-picks)"
