In reveal-mode hidden parts gets shown when you found a hit there with
isearch. That is very useful.

However when you edit such parts they normally do not get visible even
if reveal-mode is on. This is a problem for example if you are using
viper and do "o" to open a new line below the current line when the
lines below are hidden. (I am sure there are other examples with
default Emacs commands. Please give examples.)

This hits quite often in org-mode.

Could we please add some mechanism to show the point when this happen?

reveal-mode should unhide the text, assuming that point is within it.

Can you provide a recipe to reproduce the problem?

That's what reveal-mode does, normally.

Eh, sorry, you are right. reveal-mode takes care of this. I thought I
had it on, but for some reason I had commented it out.

I think I got confused by the similar mechanism in isearch that is on
by default. That it is on by default seems good. What is the reason
reveal-mode is not on by default? (I have a feeling there was some
small problem, but I can't remember now.)

Good, so I can close the bug.

I suspect it could take some more work to make it robust enough to be ON
by default.  But I encourage everyone to (global-reveal-mode 1) in their
.emacs and post patches for the problems they encounter.
