Unhiding edited areas

[Martin Pohlack <mp26@os.inf.tu-dresden.de>]

Hi there,

I'm using undo from time to time in org-mode buffers and sometimes the
area covered by the undo step is hidden (folded away) at the undo
time.  I feel somewhat uncomfortable in this situation as I,
apparently, rely on the visual appearance of the buffer when undoing
and redoing several steps.

For interactive search, the area around point is unfolded incrementally.

Is there a way to always show the area where edits are done?

Cheers,
