bug#20183: 24.4.91; No resize handle to adjust width of Emacs windows

[N. Jackson]

There are resize handles to adjust the height and width of an Emacs
frame; and there is a resize handle to adjust the height of an Emacs
window (when there is more than one window tiled vertically
(above/below) on a frame); but there is _no_ resize handle to adjust the
width of an Emacs window (when there is more than one window tiled
horizontally (side-by-side) on a frame.

This can be observed from emacs -Q.

I'm not sure if this is a bug or a missing feature.
