Support empty lines in bullet list

[wander]

When creating a slide with few bullet points, I would like to add extra vertical space between them.

Syntax example 1:

-foo

-bar

-baz

Syntax example 2: (this one is already possible but still adds bullet points --> bullet points shall be invisible if line is empty)

-foo
-
-bar
-
-baz

Alternatively assign vertical space automagically if there are few bullet points.

This is a task for CSS. The bare bones way is to use

-;padding-bottom:18px foo

or

-;line-height:50px foo

If this is too much typing, then a CSS class should be added

li.dbl {

padding-bottom:padding-bottom:18px;

}

Then in markdown you write

-;dbl foo

Adding special meaning to newlines would lead to an ambiguous grammar. The other option is not intuitive either.
I could only imagine

-foo
.
-bar
.
-baz

and treat it as a general rule that a line that contains only a dot is treated as an indicator for more vertical space. But this is a non-trivial change in the grammar.

CSS should serve my purpose. Thanks!
