Inline <script/> tag in text breaks XHTML

[robertaccettura]

Here's a sample of the code entered:

This is some text with a script in it<script type="text/javascript"> printEmailMsg(); </script>.

The output expected (and done in 2.0.x) is:

<p>This is some text with a script in it<script type="text/javascript"> printEmailMsg(); </script>.</p>

Actual output in 2.1 is:

<p>This is some text with a script in it<br />
<script type="text/javascript"> printEmailMsg(); </script>

<p>.</p>

This is obviously broken, and breaks older content. <p/> is not closed, shouldn't have a <br/> inserted.
