<p class="purpose">To spool error messages into the HTML report.</p>
<p class="commentary firstcommentary"><a id="SP1" class="paragraph-anchor"></a><b>&#167;1. </b>Foundation has a perfectly good library of code for error messages, but
we won't use it, because we need to do something unusual with them: they
must not only be printed to standard error, but also spooled into HTML
format for possible use on a status HTML page. Hence this section.
</p>
<p class="commentary">Inblorb is in any case only minimally helpful when diagnosing problems,
because it's intended to be used as the back end of a system which only
generates correct blurb files, so that everything will work &mdash; ideally, the
Inform user will never know that Inblorb exists.
</p>
<p class="commentary">First, the current position of errors is recorded so that we can report
the source of the trouble:
