That's exactly what I meant.  pop-to-buffer doesn't allow configuring its
behavior to display the source buffer in the same Help window.  I don't argue
for changing its default behavior.

How about adding a new user option, e.g `same-window-regexps-from'?
By analogy with `same-window-regexps' it will contain a list of regexps
saying that displaying a buffer from these buffers should appear in the
same window.
