The client passes the decimal point that it wants in to the CSV writer,
so the code needs to change whatever decimal point it ends up with by
that one.  I applied a patch that implements the behavior.

(If the decimal point and the field delimiter end up the same, that's
still OK: it will just cause fields that contain a decimal point to be
quoted.)
