     <code class="function">errhint(const char *msg, ...)</code> supplies an optional
     <span class="quote">“<span class="quote">hint</span>”</span> message; this is to be used when offering suggestions
     about how to fix the problem, as opposed to factual details about
     what went wrong.
     The message string is processed in just the same way as for
     <code class="function">errmsg</code>.
