Oh, I didn't know we had a mention of random there too. New text is:
<title>The <quote>random</quote> test</title>
<para>
There is at least one case in the <literal>random</literal> test
script that is intended to produce random results. This causes
random to fail the regression test occasionally. Typing
<programlisting>
diff results/random.out expected/random.out
</programlisting>
should produce only one or a few lines of differences. You need
not worry unless the random test always fails in repeated
attempts.
</para>
I wanted to reduce the frequency of random failure by doing more random
tests, and reduce the amount of confusion when it fails. I see no way
of preventing it from ever failing.
