Perhaps "git range-diff HEAD@{1}...HEAD" being an empty is a sign
that either the user intentionally or accidentally did not do
anything other than "touch"ing the commit.

"git commit --amend --[no-]range-diff" that shows what you changed
with the amending may be an interesting possibility; I am not yet
ready to seriously encourage anybody to explore it, though, because
"git diff HEAD@{1}" is much easier to see what code got changed, but
one (and probably only) downside is that it does not cover the
change in the log message.
