Hi,

I use this to always display the *Help* buffer in the selected window,
or to reuse existing window displaying the same buffer:

  (add-to-list 'display-buffer-alist
               '("^\\*Help\\*$" . ((display-buffer-reuse-window
                                    display-buffer-same-window))))

With this, whenever I forget the keybindings available during
query-replace and hit '?' to get help, the help buffer is displayed in
the main window which shows the replacements to be performed.  When I
try to bury the help buffer with 'q', it doesn't do what I intended - it
quits the query-replace session.  The same thing happens when I try to
switch to the main window with 'C-x o' and manually kill the buffer.

The only thing that works really, is to enter recursive edit, kill the
help buffer and exit-recursive-edit.

This happens because the help buffer generated by perform-replace is
named "*Help*" and my display-buffer rule matches it.  I work around
this by adding an additional rule to display-buffer-alist which checks
if the help buffer was created by perform-replace.  It's ugly:

  (defun my//display-buffer-help-for-query-replace-condition (bufname action)
    (and (string-match-p "\\*Help\\*" bufname)
         (catch 'res
           (mapbacktrace (lambda (_evald func _args _flags)
                           (when (eq func 'perform-replace)
                             (throw 'res t)))))))
  (add-to-list 'display-buffer-alist
               '(my//display-buffer-help-for-query-replace-condition
                 . (display-buffer-pop-up-window)))


There are a couple of ways to improve behavior of perform-replace:

- Use a different name for the query-replace help buffer (patch attached)
- Make 'C-l' or some other key bury the help buffer, if it was displayed
  in the main window
- Make '?' toggle visibility of the help buffer
- Allow switching windows in query-replace
- Display the help message in the minibuffer

To solve the same problem, isearch binds display-buffer-overriding-action
to isearch--display-help-action with '(nil (inhibit-same-window . t))
that forces the *Help* buffer to be displayed in another window.

Thanks for letting me know.  I'm attaching a different patch which uses
display-buffer-overriding-action.  Does it look OK?

I tried your patch, and see that it solves the problem.
My customization binds "*Help*" to display-buffer-same-window too,
so I had the same problem, and my old solution was to refrain
from using help in query-replace :)  Thanks for finally fixing this.

Thanks for testing, Juri.

Since the patch fixes the bug, will it be applied any time soon?

Please consider retitling the bug, as it (the solution, at 
least) is not about renaming the *Help* buffer.

The problem is apparently not the buffer name but the
window, and the  solution seems to be to use a
different window.

(I would likely have objected if the buffer were to
be renamed, rather than a different window being used.)

A worse problem is that when 'log-edit-insert-changelog' inserts the author,
it removes the 'log-edit-summary' face from the summary line, this is confusing.
This patch fixes this usability issue by inserting the explicit Summary: field
in case if other fields are inserted:
