Thats from xo-final.dtx, so it got overwritten anyway by xo-new.dtx. There
it escaped my testing. But as further testing showed, it was also the
wrong cure for a misdiagnosed bug. Not floats starting in column 2 and up
were displaced, but floats spanning  2+ columns.
Here's  a fix for xo-new.dtx, but I am still not shure wether the fixing
is done in the right place at all.
