Hello :)

`info-lookup' (from info-look.el) does not respect `display-buffer-alist'.

To reproduce an example, open some buffer in fundamental-mode, evaluate

   (setq
     display-buffer-alist
     '((t (display-buffer-reuse-window display-buffer-same-window))))

and type

   C-h S c-mode RET sin RET

We'd expect the *info* buffer to be shown in the current window. Instead, a new window is created. This is because info-look.el does neither call display-buffer, nor does it take display-buffer-alist into account by itself:

   https://git.sv.gnu.org/cgit/emacs.git/tree/lisp/info-look.el?h=605414d018da47f99dec5019142f584b6eb174c8#n395

Kindly
Mekeor

Thanks.

You should be able to get what you want by customizing the option
info-lookup-other-window-flag to the nil value.

I'm not sure it is reasonable to expect every command to use
display-buffer or its family for every window it displays.

Thanks, Eli. In that case I'll just close this issue. Especially 
since I'm satisfied with info-lookup-other-window-flag. Sorry for 
the noise. :)

It wasn't noise, and you have nothing to be sorry about.

Thank you for your interest in Emacs.
