-			 * lie and tell it that the console is
-			 * `/var/log/console`.

-			 * Furthermore, part of the test suite for
-			 * fmtmsg() attempts to verify that it returns the
-			 * correct error codes when it fails to write to
-			 * the console (either MM_NOCON if it successfully
-			 * wrote to stderr or MM_NOTOK if it didn't).  It
-			 * does this by replacing what it thinks is the
-			 * console with a directory, rather than a regular
-			 * file, in order to trigger a failure from
-			 * fopen().
-			 *
-			 * In order to pass this misbegotten test, we
-			 * check to see if `/var/log/console` exists and
-			 * is a directory.  If that is the case, we try to
-			 * open that instead of the real console.  We will
-			 * of course fail, but that's what we're expected
