Tells whether to interpret empty lines or not. This parameter is taken into account while using scsv::read or scsv::save. Since empty lines might break data integrity (number of columns mismatch), they are ignored by default. When such row is found, W_STR_EMPTY warning is issued.

If underlying boolean is set to true, empty lines are taken into account. Empty row is allocated for them and internal scsv::state is kept in OK condition.

Function returns the same boolean value that was passed as el parameter.
