* Customize how xrefs are followed in help-mode?

It's always bothered me that following a function/variable definition
button from a *Help* buffer goes to the file in a separate window -- I
almost always want to re-use the *Help* window.

Essentially, help-mode.el:209 hard-codes the use of `pop-to-buffer', I'd
like to be able to use `pop-to-buffer-same-window'.

From a user's standpoint, I guess what I'd prefer is to be able to give
a prefix arg to RET when following the button, but I don't see any way
of passing that arg down, plus there's no good equivalent for the mouse
click.

Would people consider a customization option to control this?

Eric

I think this the same as Bug#35487, where there are some suggestions
to use display-buffer-alist to control this.

Oh weird, Tak Kunihiro posted his final solution (which I'm stealing)
just a few hours ago, dunno how I missed that.

Thanks!

I'll just add an explicit link for posterity: https://debbugs.gnu.org/35487#20

While it doesn't offer such a thing yet, it should be easy to extend
`other-frame-window` to also offer a `ofw-same-window` prefix command,
to solve this dilemma once and for all.

The last solution on #35487 is pretty concise, though...

To depend on a prefix arg is a good idea.

  (defun display-buffer-from-help-p (_buffer-name _action)
    (when current-prefix-arg
      (with-current-buffer (window-buffer)
        (eq major-mode 'help-mode))))

  (setq display-buffer-alist '((display-buffer-from-help-p
                                display-buffer-same-window)))

That's a nice solution, too, thanks!
