In several cases our text files had commentary like this:
# Egypt to cancel daylight saving time
# <a href="http://www.almasryalyoum.com/en/node/407168">
# http://www.almasryalyoum.com/en/node/407168
# </a>
where lines 2 and 4 let the file be viewed by a browser with the
URL being clickable. In practice this approach does not work with
many modern browsers (I tested with Firefox and with Chrome) and
it clutters up the data, so in cases like the above this patch
removes lines 2 and 4.
