28.0.50; [eldoc] Impossible to avoid creating the *eldoc for xxx* buffer |

With eldoc-mode, a buffer like *eldoc for setq* is created and updated
all the time, is it possible to stop it? since I don't need the
buffer at all. If the buffer must be created, maybe make it uninteresting by
prefixing the buffer name with a space.
I've tried the following which does not work.
(remove-hook 'eldoc-display-functions #'eldoc-display-in-buffer)

I just pushed a commit fixing this. Please try it out. The idea is that
if you never M-x eldoc or M-x eldoc-doc-buffer, you are never bothered
by that buffer. If you do call these commands, the buffer becomes
"interesting" and shows in the normal buffer list, until you kill it,
after which it re-created in space-prefixed "uninterested" form again.
I'm closing this bug, but we could reopen if the problem isn't fixed.
