Position-registers and bookmarks should be made to work in such cases
as well.  I think a somewhat unified approach (also unified with the
help-xref-stack) would be welcome.
When I say unified, I mean at the implementation level.  Every "view"
such as an info-node, a help item, an email, ... should set
a `here-is-how-to-find-me-back' variable (that variable is called
`help-xref-stack-item' in help-mode).
