BTW, what you do here reveals the basic problem with how Emacs currently
handles fringes and scrollbars.  When you remove the scrollbars the
Emacs frame shrinks.  When you remove the fringes it does not shrink.
Yet, when changing frame sizes we are expected to handle fringes and
scrollbars alike: They are no text, they are no windows and therefore
should not be counted in the width of the frame's text area.  This
cannot ever work right.
