[PATCH] Fixing endless loop of org-reveal with inline-task

[Marc-Oliver Ihm <marc@ihm.name>]

Hi all,

If I have this simple buffer:

* foo

*************** bar
*************** END

i.e. one node with a single inline node.
If now I place the cursor at the end of the buffer and invoke (org-reveal), I get stuck in an endless loop.
(of course one needs to (require 'org-inlinetask) before)

I think this can be fixed by patching org-goto-sibling as shown below (against HEAD). Could you please consider accepting this patch, as the problem hits me every few days.

Background: In my opinion the current behavior of org-goto-sibling is wrong if the cursor is at the end of the given example-buffer. In that case cursor gets placed at the start of the END-line and the return value is t. This contradicts the documentation, which states "Returns t
when a sibling was found.  When none is found, return nil and don’t
move point."
My patch corrects this, so that when invoking org-goto-sibling in this case, cursor is not moved and return value is nil.
I did not notice any negative effects with this patch in the past few weeks.

Thanx a lot
Marc Ihm
