I isolated a bit more the problem:
On a "fresh-from-the-archive-distrib" PmWiki installation, I added the
following config.php:

  <?php if (!defined('PmWiki')) exit();
  $DefaultPasswords['admin'] = crypt('foo');
  $EnableDiag = 1;

edited a bit, finishing with the "Save and Edit" button to obtain the
"pat=/^\(:e_preview:\)/e" message.

This behavior occurs only when $EnableDiag is set to 1.
