Definition lists

[Michel Fortin]

Since we are talking about definition lists, there is an issue I'm not 
sure how to solve about the current syntax. In the syntax description, 
I give an example of lazy-indentation:

	Apple
	:   Pomaceous fruit of plants of the genus Malus in
	the family Rosaceae.
	Orange
	:   The fruit of an evergreen tree of the genus Citrus.

Then I say that definition lists can contain multiple definitions for 
one term and give that example:

	Apple
	:   Pomaceous fruit of plants of the genus Malus in
	    the family Rosaceae.
	:   An american computer company.
	Orange
	:   The fruit of an evergreen tree of the genus Citrus.

But what happens if you mix the two? Let's see...

	Apple
	:   Pomaceous fruit of plants of the genus Malus in
	the family Rosaceae.
	:   An american computer company.
	Orange
	:   The fruit of an evergreen tree of the genus Citrus.

This isn't right at all. PHP Markdown Extra 1.0b2 sees three terms, and 
we get this:

	<dl>
	<dt>Apple</dt>
	<dd>Pomaceous fruit of plants of the genus Malus in</dd>

	<dt>the family Rosaceae.</dt>
	<dd>An american computer company.</dd>

	<dt>Orange</dt>
	<dd>The fruit of an evergreen tree of the genus Citrus.</dd>
	</dl>

Now, I see two ways to solve that: either we make indentation 
mandatory, or we say definition terms must be preceded by an empty 
line. I think the first goes against current Markdown behaviours, but I 
also happen to like the compact form which is nice for lists with many 
short definitions.

Any ideas?
