feat: Avoid using display-buffer-overriding-action with ghostel

[djr7C4]

Using display-buffer-overriding-action breaks other-window-prefix and
same-window-prefix. A simpler solution is to use
(pop-to-buffer (ghostel-create)).

Thanks! I imported your commit, with your authorship, on the next branch, which will be merged to main soon. I adapted it on the way: it checks for ghostel-create (ghostel 0.52.0 or later) after requiring ghostel, since that function is not autoloaded, and it passes the pop-up window as ghostel-create's display action so the terminal is sized to the window that shows it, while other-window-prefix and same-window-prefix still win.

Sounds good. I'll look forward to seeing it once it's merged. The next branch seems to be local only.

It's on main 🎉

Will cut 2.6.0 soonish after a few more fixes and maybe feedback from users if smth breaks.

[djr7C4]

Nice. I'm checking out the new features. Maybe add a 2.6.0 tag if you like.

[djr7C4]

Oh, nvm. For some reason I was thinking this was already 2.6.0.
