The vertical border is not shown in the tab line. See
no-window-divider-mode.png for an example. On the other hand, the
window divider is (when using window-divider-mode). See
window-divider-mode.png for an example.

I think it would make sense to show the vertical border in the tab
line, since it is still part of the window. On the other hand, the
mode line is also part of the window but the vertical border is not
shown there. While it is possible to customize tab line to do this,
this is a minor UI detail that could be there from the start. Other
editors show their corresponding window dividers in their
corresponding tab line, which leads to a more consistent UI (albeit a
small detail).

This is the reason why the vertical border is not shown in the tab line -
for consistency with the mode line and the header line.

Patches welcome to show the vertical border everywhere:
in the mode line, header line, tab line.

Is there a simple way to draw 1 pixel lines or 1 pixel spaces? I am
currently adding a vertical border in my tab-line customization with a
XPM, but that doesn't sound ideal. How's the original vertical border
drawn?
