This is copied from the [[+ rule in stdmarkup.php:

Markup('[[|+', '<[[|',
  "/(?>\\[\\[([^|\\]]+))\\|\\s*\\+\\s*]]/e",
  "Keep(MakeLink(\$pagename, PSS('$1'),
                 PageVar(MakePageName(\$pagename,PSS('$1')), '\$Title')
                ),'L')");

So something like this should theoretically work (just changed the
pattern to not look for "|+"):

Markup('[[title', '<[[|',
  "/(?>\\[\\[([^|\\]]+))\\s*]]/e",
  "Keep(MakeLink(\$pagename, PSS('$1'),
                 PageVar(MakePageName(\$pagename,PSS('$1')), '\$Title')
                ),'L')");

Of course you're going to have to disable the "[[" rule so they don't
fight over the free links...  Search for DisableMarkup() for that -- I
think it's as simple as:

DisableMarkup('[[');
