Shift-enter in <li> causes <p>

[novasource]

If I am in a list item (<li>), and I press shift-enter, the resulting tag should be a <br>.

If I press shift-enter twice, the resulting tags should be <br><br>.

Instead, WordPress is entering <p> tags.

E.g., here's what I should get:

<li>Text text text text.
<br>
<br>Text text text text.</li>

Instead, I get this:

<li>Text text text text.
<p>Text text text text.</p></li>

Surely two newlines should produce this:

<li>
<p>Text text text text.</p>
<p>Text text text text.</p>
</li>

Replying to ionfish:

Surely two newlines should produce this:

<li>
<p>Text text text text.</p>
<p>Text text text text.</p>
</li>

I think that for that to be valid, the default list code would have to be <li><p>Text text text text.</p></li>.

Simply translating shift-enter to <br> seems more straightforward.

This is how the js version of wpautop currently works, it sees 2 <br /> as 2 new lines '\n\n', so makes a <p>.

Punting to be evaluated in next development cycle due to time constraints.
