Nested lists and blank lines

[David Reimer]

I have recently begun using Markdown + PHP Md Extra + SmartyPants in
the Symphony XML-based CMS. I'm not sure if this is a Symphony
question, or one that can be answered here. I hope someone will tell
me. :) I've done my best to find an answer in the online
documentation, but drawn a blank.

When I use nested lists -- it doesn't matter whether <ol> or <ul>,
there is always a blank line forced after the second level list is
complete before returning to level one. Examples:

MARKDOWN =
Ex. 1:
1. one
  2. one-one
  2. one-two
1. two
1. three

Ex. 2:
- first
- second
  + and this
  + and that
- third

OUTPUT =
Ex. 1:
1. one
   1. one-one
   2. one-two

2. two
3. three

Ex. 2:
* first
* second
   o and this
   o and that

* third


HTML PRODUCED =
Ex. 1:
        <ol>
<li>one

<ol>
<li>one-one</li>
<li>one-two</li>

</ol></li>
<li>two</li>
<li>three</li>
</ol>

Ex. 2:
        <ul>
<li>first</li>
<li>second

<ul>
<li>and this</li>
<li>and that</li>
</ul></li>

<li>third</li>
</ul>

Is the "blank line" expected? Can I get rid of it?!

Thanks for any help with this!
David.
