Folding whitespace at the end of a tree

[Kjell]

Hello,

sometimes I'd like my trees to be displayed with a blank line at the end 
of a subtree to improve visability.

So it should look like this when unfolded once:

* Headline 1
** Subheadline 1.1
** Subheadline 1.2

* Headline 2

However with org-cycle-seperator-lines at its default value of 2 a 
single blank line gets folded into Subheadline 1.2:

* Headline 1
** Subheadline 1.1
** Subheadline 1.2
* Headline 2

When I set the variable to 1 a single blank line is not folded into 
Subheadline 1.2 but leads to a blank line between Headline 1 and 
Headline 2 when folded:

* Headline 1

* Headline 2

but it should look like this:

* Headline 1
* Headline 2

Is there any way to achieve this behaviour or is it impossible for org 
to know where the blank line belongs?

Thanks,
