Got a quick feature request.

Over the years I've put more and more information into the header line, and at some point I wanted to get that quick visual indicator of selected vs non-selected windows when I glanced at the header as I already got from the mode line.

This was surprisingly hard to achieve!  For a few years I used an ugly `buffer-list-update-hook` hack.  Then a few months ago I got adventurous and found that it actually wasn't as hard as I'd feared to hack these into the C source.

The new faces both inherit from the current `header-line` face, so there shouldn't be any visible impact if users don't customize the new faces.  For cases like mine it's easy to customize header-line-inactive to inherit from mode-line-inactive.

Thanks in advance for your attention and feedback,

Trevor
