The face `vertical-border' inherits from `mode-line-inactive'
which is grey by default, so `window-divider' could do the same.

PS: I don't understand why there are two identical faces
`vertical-border' and `window-divider'.

With no scroll bars, evaluating

  (set-frame-parameter (selected-frame) 'right-divider-width 0)

uses the `vertical-border' face, and allows resizing windows
by dragging the vertical line.

And after

  (set-frame-parameter (selected-frame) 'right-divider-width 1)

`vertical-border' is replaced by `window-divider' with exactly
the same behavior.  Shouldn't these faces be merged?
