OK, I just hope the method mentioned at the beginning of this thread is a safe way to clean up the 1500 entries from the three affected tables, a total of 4500 rows, for those who now wish to.
A quick slob check of how many rows my small unaffected (post 1.8-1.9 boundary) wiki has: $ mysqlshow --count transgender| perl -nlwe 'next if / set./;if(/(\d+)\D+$/){$tot+=$1};END{print $tot}' 328
