For some reason, the rows in the tables in the generated documentation get doubled with the new std.ddoc which Andrei has been working on for www.d-programming-language.org. For instance, look at opCmp on http://www.d-programming-language.org/phobos/std_datetime.html . It should have 3 rows, but it has 6.
It turns out that a comma was missing in the table, and that somehow caused it to double.
