Documentation
Default positions of window dividers.
Possible values are bottom-only (dividers on the bottom of each
window only), right-only (dividers on the right of each window
only), and t (dividers on the bottom and on the right of each
window). The default is right-only.
The value takes effect if and only if dividers are enabled by
window-divider-mode(var)/window-divider-mode(fun).
To position dividers on frames individually, use the frame
parameters bottom-divider-width and right-divider-width.
This variable was added, or its default value changed, in Emacs 25.1.
Probably introduced at or before Emacs version 25.1.
