I did some testing, and here's what I got.

Both

<informalexample>
<programlisting>for tty in /dev/ttyv?
do
  vidcontrol VGA_80x60 &lt;$tty &gt;/dev/null 2&gt;&amp;1
done</programlisting>
</informalexample>

And:

<informalexample>
<programlisting>
for tty in /dev/ttyv?
do
  vidcontrol VGA_80x60 &lt;$tty &gt;/dev/null 2&gt;&amp;1
done
</programlisting>
</informalexample>

I got:

            <div class="INFORMALEXAMPLE">
<pre class="PROGRAMLISTING">
    for tty in /dev/ttyv?
    do
      vidcontrol VGA_80x60 &lt;$tty &gt;/dev/null 2&gt;&amp;1
    done
</pre>
            </div>

For <screen> -

<informalexample>
<screen>bash$ <userinput>vidcontrol VGA_80x60</userinput></screen>
</informalexample>

And

<informalexample>
<screen>
bash$ <userinput>vidcontrol VGA_80x60</userinput>
</screen>
</informalexample>

both gave:

        <div class="INFORMALEXAMPLE">
<pre class="SCREEN">
    bash$ <tt class="USERINPUT"><b>vidcontrol VGA_80x60</b></tt>
</pre>
        </div>

If noone has any other evidence, I'd like to propose the more
readable form.

I get the impression it just ignores a starting and ending empty
lines - blank (ie, with spaces) lines still show up.
