hook_help removed

Hook_help() gets removed completely.
Marking this as critical since removing the function is not better than making a comment about it. I was, until today, under the wrongful impression that hook_help was canned.

Deadwood:

/**
 * Implementation of hook_help().
 * @param $section
 *    The name of the section or url of the page for which help should be displayed.
 */
function foo_help($section = 'admin/help#foo') {
  switch ($section) {
    case 'admin/help#foo':
      return t('Foo can be very helpful.');
  }
}

Goodwood:

/**
 * Implementation of hook_help().
 * @param $section
 *    The name of the section or url of the page for which help should be displayed.
 */

Even the extra line from deadwood after the function was removed.
Hope this helps shed some light...
I had a look at the implementation to see if I can spot anything amiss but alas, my regex kunfu is lacking.

Thank you all for this very useful project!
