Links to form in no-results messages broken

Problem: Displaying empty results lists produces "There are no submissions for this form." followed by a "View this form" link that is an absolute URL, therefore breaks if Drupal is installed in a subdirectory.

Fix:

For the two files...
sites/all/modules/webform/views/default_views/webform_submissions.inc
sites/all/modules/webform/views/default_views/webform_results.inc

Replace the line...
$handler->display->display_options['empty']['area_text_custom']['content'] = 'There are no submissions for this form. View this form.';

With the line...
$handler->display->display_options['empty']['area_text_custom']['content'] = t('There are no submissions for this form. View this form.', array('!url' => url('node/')));
