* [Bug libfortran/25425] New: F95 and F2003 differ on list-directed output for 0.0

It seems that, according to F95, list-directed formatting of zero must behave
as if formatted with the E descriptor (0.0E+00) while F2003 requires an F
format behaviour (0.0). See message
<1134632379.672465.126120@z14g2000cwz.googlegroups.com> on comp.lang.fortran
("writing formatted zeros with implicit formats", by robert.corbett@sun.com).
We currently implement the F2003 behaviour, independently of the -std flag.
$ cat a.f
PROGRAM MAIN
PRINT *, -2.1, -1.2, 0.0, 1.1, 2.2
END
$ gfortran a.f && ./a.out
-2.100000 -1.200000 0.000000 1.100000 2.200000
$ ifort a.f && ./a.out
-2.100000 -1.200000 0.0000000E+00 1.100000 2.200000

Sorry to interfere, Jerry, but I had some time and decided to write that patch.
If you already had a patch for this, I'd be interested in knowing the approach
you chose.

Not a problem, I only had a first look at this and calculate G format caught my
attention, that was as far as I got. I was going to have to study the -std
flag stuff to see where to go there. Glad to see you in action!
