Drush not reading config file from top-level /drush folder within Drupal install? I'm trying to have localized drushrc.php configurations and alias configurations per site I'm working on, but no matter what I'm trying right now, drush refuses to find or load my drushrc.php configuration file.

Based on #2 in the example configuration file found here:
https://github.com/drush-ops/drush/blob/master/examples/example.drushrc.php

I should be able to place a drushrc.php configuration file in a top-level /drush folder location:


$DRUPALROOT/../drush/drushrc.php (top-level parent above root folder)


No matter what I'm trying drush never seems to detect the configuration file in this location when I do a drush status in the drupal root folder. Everything works fine if I place drushrc.php within my home folder (~/.drush/drushrc.php) or in a sub-folder of my install (*$DRUPALROOT/drush/drushrc.php). Problem is I don't want there and would like it in a top-level folder above my root install! 

Is there a secret to getting drush working based on this ?! I've tried drush cc drush every time I move my configuration around but it's never found!

On Mac OS X if it matters? Please help!
Sorry, there is a typo in Drush preventing this:

This fix should be in the next version of Drush.  Sorry for the inconvenience.
