NAMELIST input and &

Hi,

Although the following code seems valid:

implicit none

logical :: l = .FALSE.
integer :: i = -1
real :: r = 0.
character(5) :: c = ''

namelist /input/l, i, r, c

open (UNIT = 101, FILE = 'input.dat', STATUS = 'OLD')
    read (101, input)
close (101)

write (*,input)
end

There should be a warning or error of some sort when reading a namelist with a non-standard termination, like for example:

&input
l = T, &
i = 1,
r = 2.,
c = '12345'
/

The warning is especially useful if the -stand option is given during compliation.  Here's what compiling with gfortran shows, followed by ifort's equivalent:

...:~$ ll `which gfortran`
lrwxrwxrwx 1 root root 12 May  3 12:57 /usr/bin/gfortran -> gfortran-4.8*
...:~$ ll `which ifort`
-rwxr-xr-x 1 root root 4013312 Apr 25 08:19 /opt/intel/composer_xe_2013_sp1.3.174/bin/intel64/ifort*
...:~$ gfortran test_namelist.f90
...:~$ ./a.out
At line 11 of file test_namelist.f90 (unit = 101, file = 'input.dat')
Fortran runtime error: namelist not terminated with / or &end
...:~$ ifort -stand test_namelist.f90
...:~$ ./a.out&INPUT
 L       = T,
 I       =          -1,
 R       =  0.0000000E+00,
 C       =
 /

As of today, I know ending the namelist with & is an extension, but since I shouldn't have to be aware of every single extension in ifort (or gfortran), I just spent two days trying to find a non-existent bug in the code.
