Create a 3-line file named foobar.org containing exactly this:
* foo
** bar
baz
(So the first character of the file is *.) Type
emacs -Q foobar.org
and type
M-x reveal-mode RET TAB M-g g 2 RET
which will activate reveal-mode, fold everything and go to the
beginning of the second line ("** bar").
Now the following is displayed:
* foo
** bar...
and the point is at the beginning of "** bar".
So far, everything is normal.
But now, pressing TAB does nothing, while it should unfold the second
heading. In fact, moving around, folding/unfolding the first heading, etc,
will never fix the now broken TAB: from now on, if "** bar" is folded and
point is at the beginning of it, TAB will not unfold it (though C-e will).
