++    extension. Allow to detect these early to avoid going through the
++    whole list of detectors. This also avoids the risk of misdetection
++    as something else, as there are some formats that are text files and
++    the detection is just a heuristic (e.g., wp1 or wp42 supported by
++    libwpd). -->
