default.sites.php typo in example paths.

default.sites.php shows this example for mapping discovered conf paths to custom site directories:

 * $sites = array(
 *   'devexample.com' => 'example.com',
 *   'localhost/example' => 'example.com',
 * );

The slash in localhost/example obviously has to be a dot - conf_path() uses only dots as token separators, since this name is intended to be an actual folder name and can't contain slashes.

This is one of those "save the devs ten minutes of confusion" fixes.
