I had the impression that "git show" was an older command, now
replaceable by "git log" with some options.  Is my impression right?

Isn't there a difference between "git diff" and "git diff HEAD" where
the first would show the changes between the working tree and the index,
while the latter would show them between the working tree and the latest
commit (HEAD, as you said)?
