Newer versions of Markdown.pl and PHP Markdown do allow the trailing
'[]' to be omitted.

    <p><a href="/url">hi</a></p>
 
I agree that without this style of reference links, it would make more
sense to distinguish between link text and 'refnames'. But this style of
link gives a reason not to distinguish them.
