Better to make it opt-out because currently display of excluded buffers
on the tab-line is too glitchy.  Example:

0. emacs -Q
1. M-x global-tab-line-mode RET
2. C-x b foo RET
3. C-x b SPC *bar* RET
4. C-x <left>
   Now the buffer name " *bar*" is visible on the tab-line.
5. C-x <left>
   But now " *bar*" suddenly goes away.

This is because handling of excluded buffers is hard-coded
in many window.el functions.

So not showing excluded buffers by default will avoid this snag.
