[Conkeror] [PATCH] Provide the buffer number and number of buffers in the modeline.

[David Kettler]

This provides a count like [2/5] in the mode-line.  It's probably not
useful when using the tab bar; that provides more visual feedback.

Enable using the following in your rc:

  add_hook("mode_line_hook", mode_line_adder(buffer_count_widget), true);

I don't use anything like this in emacs.  I think in a web browser I
tend to have a lot more temporary buffers and this helps me keep track
of what I still need to look at.
