Drush perm-grant not working for permissions with spaces in them

Considering the fact that most modules define permissions with spaces in them, this is pretty useless without this working. Fortunately, the fix for it is pretty easy. I don't know the best way to create a patch so I am just putting the updated drush_permissions_api_perm_grant() function here and hoping someone can create the actual patch for it.

function drush_permissions_api_perm_grant() {
  $args = func_get_args();
  $role = $args[0];
  array_shift($args);
  // The $args array splits command line arguments on the spaces. Permissions may have spaces in them and are to be entered in a comma separated list.
  $perms = explode(',', implode(' ', $args));
  $module = drush_get_option('module');

  if ($module) {
    permissions_grant_all_permissions_by_module($role, $module);
    drush_print(dt('Granted all !module permissions to !role.', array('!module' => $module, '!role' => $role)));
  }
  elseif ($perms[0] == 'all') {
    permissions_grant_all_permissions($role);
    drush_print(dt('All permissions granted to !role.', array('!role' => $role)));
  }
  else {
    permissions_grant_permissions($role, $perms);
    drush_print(dt('Specified Permissions granted to !role.', array('!role' => $role)));
  }
}

I think that the perm-revoke command probably needs a similar fix. I tested the above and it worked for me.
