Of course, you mean below negative seven, but the other half of cases is
almost suggested by the custom quote there with the negative in front of
the first arg and then the same positive values on the right.
It was so simple to write a fortran program that the busts the C int
datatype. One thing I dislike so much about c is struggling with the
format specifiers with printf, while with fortran it's just print * for
something quick and sleazy.
