Incorrect display of engineering format

Hi,

I'm trying to use Julia, and NumericIO in particular, to refactor some Fortran.

Julia's output is
```
10000.00 1 -500.00000E0 0.0000000E0 1.0000000E0 -510.00000E0
10000.00 2 -400.00000E0 0.0000000E0 1.0000000E0 -410.00000E0
10000.00 3 -300.00000E0 0.0000000E0 1.0000000E0 -310.00000E0
10000.00 4 -200.00000E0 0.0000000E0 1.0000000E0 -210.00000E0
10000.00 5 -100.00000E0 0.0000000E0 1.0000000E0 -110.00000E0
10000.00 6 0.0000000E0 0.0000000E0 1.0000000E0 -10.000000E0
10000.00 7 100.00000E0 0.0000000E0 1.0000000E0 90.000000E0
10000.00 8 200.00000E0 0.0000000E0 1.0000000E0 190.00000E0
10000.00 9 300.00000E0 0.0000000E0 1.0000000E0 290.00000E0
10000.00 10 400.00000E0 0.0000000E0 1.0000000E0 390.00000E0
10000.00 11 500.00000E0 0.0000000E0 1.0000000E0 490.00000E0
```
from the code fragment
```
oline = @sprintf(" %12.2f %4d", line, tndx)
s = formatted(txdp.l.e, :ENG, ndigits=8, charset=:ASCII); oline *= lpad(s, 15, ' ')
s = formatted(txdp.l.n, :ENG, ndigits=8, charset=:ASCII); oline *= lpad(s, 15, ' ')
s = formatted(txdp.l.z, :ENG, ndigits=8, charset=:ASCII); oline *= lpad(s, 15, ' ')
s = formatted(rxdp[jr].l.e, :ENG, ndigits=8, charset=:ASCII); oline *= lpad(s, 15, ' ')
s = formatted(rxdp[jr].l.n, :ENG, ndigits=8, charset=:ASCII); oline *= lpad(s, 15, ' ')
s = formatted(rxdp[jr].l.z, :ENG, ndigits=8, charset=:ASCII); oline *= lpad(s, 15, ' ')
```

I believe that if engineering format is working correctly, the output should be
```
10000.00 1 -500.00000E+00 0.0000000E+00 1.0000000E+00 -510.00000E+00
10000.00 2 -400.00000E+00 0.0000000E+00 1.0000000E+00 -410.00000E+00
10000.00 3 -300.00000E+00 0.0000000E+00 1.0000000E+00 -310.00000E+00
10000.00 4 -200.00000E+00 0.0000000E+00 1.0000000E+00 -210.00000E+00
10000.00 5 -100.00000E+00 0.0000000E+00 1.0000000E+00 -110.00000E+00
10000.00 6 0.00000E+00 0.0000000E+00 1.0000000E+00 -10.00000E+00
10000.00 7 100.00000E+00 0.0000000E+00 1.0000000E+00 90.00000E+00
10000.00 8 200.00000E+00 0.0000000E+00 1.0000000E+00 190.00000E+00
10000.00 9 300.00000E+00 0.0000000E+00 1.0000000E+00 290.00000E+00
10000.00 10 400.00000E+00 0.0000000E+00 1.0000000E+00 390.00000E+00
10000.00 11 500.00000E+00 0.0000000E+00 1.0000000E+00 490.00000E+00
```
ie. decimal points should align down the columns as they do in Fortran.
