I am not in favour of renaming the option name "ignore", instead we can
use another style of name for the option to set the column value to NULL,
for example, "set_to_null".
(Maybe, we can make a more generic option "set_to (col, val)" that can set
the value of column specified by "col" value to the specified value "val"
(e.g. 'N/A') on a soft error, although the syntax would be a bit complex...)
IMO, it is more simple to define "ignore" as to skip the entire row rather
than having variety of "ignore". Once defined it so, the option to set the
column value to NULL should not be called "ignore" because values in other
columns will be inserted.
