Thanks.  I've committed these changes, with some exceptions:

> +the scroll bar; one often drags the scroll bar's handle, a rectangular
> +region that is within the scroll bar and that is used to represent the
> +portion of the text that is currently visible in the associated window.

I don't see the point of teaching people how to use scroll bars in the
Emacs tutorial, and anyway this is wrong for non-toolkit X builds.

I'd rather not get into this in the tutorial, where the
scroll-up/scroll-down command names are not mentioned.

This change is gratuitous, since it's more or less the same length.

I simply removed this, since the Emacs tutorial is not the place to
dispense this kind of general advice.

This is gratuitous--since this is a text file, not TeX or Texinfo, the
meaning should be fairly obvious.

Thanks for the copyedits.
