* Changes in Emacs 21.3
** Controlling the left and right fringe widths.
The left and right fringe widths can now be controlled by setting the
`left-fringe' and `right-fringe' frame parameters to an integer value
specifying the width in pixels. The default is 8 pixels. Setting the
width to 0 effectively removes the corresponding fringe.
The actual fringe widths may deviate from the specified widths, since
the combined fringe widths must match an integral number of columns.
The extra width is distributed evenly between the left and right fringe.
For force a specific fringe width, specify the width as a negative
integer (if both widths are negative, only the left fringe gets the
specified width).
** hide-ifdef-mode now uses overlays rather than selective-display
to hide its text. This should be mostly transparent but slightly
changes the behavior of motion commands line C-e and C-p.
