With the calc's *Help* buffer it's clear now that
(inhibit-same-window . t) is available for users
that have (add-to-list 'same-window-buffer-names "*Help*")
in .emacs.

But I meant that *Calculator* and *Calc Trail* windows could be
displayed with `display-buffer' and an appropriate ACTION argument.
Then users will be able to customize its default behavior.

Isn't it the goal of window related improvements to allow
customizing easily of how windows are displayed?
