Yes, I agree, and I don't need I need repeat mode for too many commands from
other window either; but since I have rebuilt the info mode itself, I have
"only" Info-mode-map, there are no "same-window/other-window" commands, and it
worked just fine with putting repeat mode on all, but that was expected. For the
record, I was able to port Info from version current master back to version 25
today. Only bad deal was a mailformad Info-spec, but everything seems to work well
when I test.

Ok. Thanks, good to know. Then I'll keep those two outside of keymap definition.

So at least in theory, by let-bidinging it to nil, it should keep prompt
on the original frame. I did just quick naive test, and ended up in debugger:

(defun info-menu-wrapper ()
  (interactive)
  (let ((minibuffer-follows-selected-frame nil))
    (with-selected-window (info-window)
      (call-interactively #'Info-menu))))

but perhaps there are more tweacks to it which I am not familiar with, so I'll
leave it at that.

About wrapping; I agree that it is messy to go through each and every command as
I did to modify them, so for old existing commands, it is definitely easier to
do the wrapping, if possible. I just hope we get a better way for future command
writing. 

Thanks for the answer
