    Dragging the thumb to the beginning of the buffer does not require

In most of the buffers I use, going to the end does not require
precision work; I just checked!

Precision work may be required if you visit a long buffer, such as the
NEWS buffer, and you are going to a point that is not quite the end.
However, I don't think the scroll bar and thumb should be adapted to
this kind of positioning.

(Note that the scroll bar and thumb work fine for positioning text in
a buffer as short as this *mail* buffer.)

Instead of using the scroll bar and thumb for precision work in a long
buffer, I use the <down> arrow key, which I have bound to:

    (defun scroll-forward-one-line ()
      "Scroll the text up one line.
    A replacement for the three keystroke sequence
    C-u 1 C-v."
      (scroll-up 1))

  (global-set-key [down] 'scroll-forward-one-line)  ; Down arrow key

and the nearly equivalent `scroll-backward-one-line', which I have
bound to the <up> arrow key.  (Interestingly, the `(scroll-up 1)'
expression does not consider a line consisting of a single, final
newline as the last line of a buffer, but the line before it, which
may also be a single newline.  I never noticed this characteristic

When I am testing a `plain vanilla' GNU Emacs stated with 

    emacs -q --no-site-file --eval '(blink-cursor-mode 0)'

I simply use the necessary three keystroke sequence.
