Make date handler custom date format translatable

The 6 year old patch to views_handler_field_date.inc does not apply to the latest views 7.x-3.x-dev and if still applicable needs reroll.

Checking patch handlers/views_handler_field_date.inc...
error: while searching for:
          if ($custom_format == 'r') {
            return format_date($value, $format, $custom_format, $timezone, 'en');
          }
          return format_date($value, $format, $custom_format, $timezone);
        default:
          return format_date($value, $format, '', $timezone);
      }

Patch rerolled.

Yeah, it really makes sense. Tested and with patch #3 this text will appear to be translatable. Thank you so much for your contribution people

Seems like a bit of a hack, wouldn't it be better to use drupal_alter().

Nevermind, seems like D8 might do it using translate, so fair enough.

Restoring status.

Should the other uses of $custom_format or $second_custom_format also be wrapped in t()?

On an aside, the logic in views_handler_field_date::render() is rather peculiar, I think I'll set up a different issue for that.

Committed. Thanks everyone.
