I'm referring to code like

<ul>
<?php foreach ($data as $value): ?>
    <li><?=3D $value ?></li>
<?php endforeach; ?>
</ul>

Currently this would produce the output

<ul>
    <li>Foo</li>
    <li>Bar</li>
</ul>

Without the trailing newline elision it would produce

<ul>

    <li>Foo</li>
    <li>Bar</li>

</ul>

I always assumed that this is the reason why we do this in the first place.
