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:

Kindly
