core-tutorial.txt: Fix showing the current behaviour.

Browse Source 
The --root option from "git diff-tree" won't do nothing
when is given to commands like git-whatchanged or git-log,
because those always print the initial commit by default.

This fixes the tutorial explaining the function of the
log.showroot configuration variable.

and you will see exactly what has changed in the repository over its
short history.
[NOTE]
The `\--root` flag is a flag to `git-diff-tree` to tell it to
show the initial aka 'root' commit too. Normally you'd probably not
want to see the initial import diff, but since the tutorial project
was started from scratch and is so small, we use it to make the result
a bit more interesting.
When using the above two commands, the initial commit will be shown.
If this is a problem because it is huge, you can hide it by setting
the log.showroot configuration variable to false. Having this, you
can still show it for each command just adding the `\--root` option,
which is a flag for `git-diff-tree` accepted by both commands.
With that, you should now be having some inkling of what git does, and
can explore on your own.
