On reflection, I think this would be a useful application of the new
display action parameter mechanism.  So I introduced a new
`inhibit-switch-frame' action alist entry; callers like occur-edit,
which require keeping focus can supply this parameter, can use this to
tell `display-buffer' to avoid stealing focus away to another frame,
even at the expense of obscuring the displayed window.
