Well, I do happen to find the current version better (perhaps easier  
to parse automatically), but that's not a big deal. However, I feel  
we should have more opinions on that change since it has a high  
impact. Especially, maybe we should have a uniform format for runtime  
error messages, e.g. I/O errors are currently using a very different  
error message style:

$ cat a.f90
  integer :: i = - 1
  open(i,status="scratch")
  end
$ gfortran a.f90 && ./a.out
At line 2 of file a.f90
Fortran runtime error: Bad unit number in OPEN statement
