This function is apparently supposed to insert a new column at position
newcol. I understand that columns (and rows and cells) start counting
at 0. What I don't understand it what happens with the indicated (col >
newcol). What this will do is shift the contents of the current column
one place to the right, for all columns to the right of the new column.
*The content of the current column doesn't get shifted* and stays in
what is supposed to be a new, empty column. It the next one that will
remain empty, but with old spacing/alignment data AFAICS.
Is this intentional or a bug?

BTW Abdel, mathed placeholders now render OK, but they still believe
their size is 0 :-(
