I sometimes do "git show -4" myself, and wondered why defaulting
to "-n 1"is insufficient, but if you do something like this to
check the tip of each branch:

	git show master next pu

this may make sense.

Otherwise, it feels to me that (I haven't had caffeine nor
nicotine yet, so I need to re-think this later) log, show and
whatchanged are the same program in disguise with different set
of defaults.

        log		--pretty
        show		--pretty -n1 -p
        whatchanged	--pretty -r

... which implies that some of them might become historical
curiosity and no real reason to teach about each of them in the
tutorial.
