Hello,

I want to implement a particular feature in org-mode that depends upon some
functionality being added to outline-mode.  (org-mode is derived from
outline-mode.)  The feature concerns display of ancestor and sibling headings
when an isearch has come to successful completion in a hidden part of the
file.  The function whose job it is to decide what to display when an isearch
has completed is called `outline-isearch-open-invisible'.  Currently, it
simply calls `(show-entry)'.  The following patch changes that function, and
adds a new variable, to allow derived modes or motivated users to implement
alternate behavior.  The default behavior remains the same, but can more
easily be reprogrammed by a derived mode.

Please comment, criticize, or enlighten.  Thank you,

John Foerch
