Hi Manish,

the line is not eaten, it is hidden by outline.  However, since you  
have not turned on outline-minor-mode, you do not see the ellipsis.

A TAB is inserted because in places where org-cycle cannot do  
anything, it emulates TAB.

I guess I should refactor org-cycle into a function that does only  
cycling, and one that does all the rest...
