org-show-following-heading

org-show-following-heading is a variable defined in `org.el'.
Its value is

((default))

Documentation:
Non-nil means show following heading when revealing a location.
Org-mode often shows locations in an org-mode file which might have
been invisible before. When this is set, the heading following the
match is shown.
Turning this off for example for sparse trees makes them very compact,
but makes it harder to edit the location of the match. In such a case,
use the command M-x org-reveal to show more context.
Instead of t, this can also be an alist specifying this option for different
contexts. See `org-show-hierarchy-above' for valid contexts.

You can customize this variable.
