Hi, Org people. Consider a header having many sub-headers, and which is closed. So I only see that header, followed by an ellipsis at the end of that line. On that header, command `C-c .' turns the initial star (or string thereof) into a dash. Now, I see an item with the same text as the previous header, still followed by an ellipsis at the end of that line. Now, TAB has no effect: it does not expand the ellipsis into the previous contents (the minibuffer writes "EMPTY ENTRY", which is likely improper)
So I have to fight a tiny bit for being able to edit the contents. I go one level up, collapse then expand, and everything becomes OK. François
