I guess it's time now to close this request.

Now pushed to master in 552d2b9083.

Pushed to master in the same commit.

> 3. There is the hook dictionary-mode-hook, and I use it to enable

Added a new hook 'dictionary-post-buffer-hook'.

> 4. 'dictionary' uses switch-to-buffer-other-window to force the output buffer
>    in another window.  Other commands use pop-to-buffer that requires just

>   The difference is in the need to add '(inhibit-same-window . nil)'.

Not changed since there are many commands that use
switch-to-buffer-other-window, so it looks like a legitimate use.

> 5. When clicking on a word link in the *Dictionary* buffer,
>    it displays the word definition only in the same dictionary,
>    while it would be better to search it in all dictionaries
>    for more coverage.

>    This is not a patch, but demonstrates the problem.
>    Maybe this should be customizable?

Added a new customizable option 'dictionary-link-dictionary'.
