 Because WordPress now uses wp-load.php to look for wp-config.php in 1
 directory up, that prevents you from installing WordPress (using the
 installer) in a sub directory of another install because the new install
 will use the wp-config.php for the other install.

 I think the easiest way to fix this is to check to see if there is another
 wordpress file 1 directory up on level with wp-config.php which would
 signify that that wp-config.php is part of another install.

 In my attached diff I am checking for the existence of wp-load.php on
 level with wp-config.php, but could be wp-settings.php or whatever.

 I marked this as Milestone 2.7.  Any chance we could work a fix in for
 2.7?  If not adjust accordingly.
