I don't want to be presumptuous, but I first published my essay with this Wikipedia reference in June 2012. I wonder if some liberal may have read my essay and responded with that edit.
As best as I can tell, the automated part had to do with the original paragraph containing in-text citations of sources rather than simple footnotes. The problem is, though, that this wasn't merely a changing of format. A lot of information was deleted and new information added or shifted around (e.g., at first I thought the Monica Lewinsky distraction charge was added, but then saw that it had just been moved).
Nearly an entire paragraph of detailed evidence of exaggeration of losses by the Clinton administration was removed (including the 500,000 claim). All that was retained -- shifted to the next paragraph -- was the mere general accusation ("U.S. President Clinton and his administration were accused of inflating the number of Kosovo Albanians killed by state forces."). That really lets the Clinton administration off the hook. Charges aren't nearly so damaging as evidence they're true. :-)
