[Bug fortran/20101] New: zero prints incorrectly with 1pe12.4

["dir at lanl dot gov" <gcc-bugzilla at gcc dot gnu dot org>]

I have never seen zero printed with a negative exponent before -

[dir:~/tests/gfortran] dir% gfortran -o format format.f
[dir:~/tests/gfortran] dir% format
  0.0000E-01
[dir:~/tests/gfortran] dir% cat format.f
      program main
      zero=0
      write(6,1000)zero
 1000 format(1pe12.4)
      end
