[Bug fortran/17709] New: NULL I/O list and Format error.

[Bug fortran/17709] New: NULL I/O list and Format error.

[wf_cs at yahoo dot com]

Test case:

program main
integer io_unit
character*80 str
io_unit = 10
open (unit=io_unit,file='in',status='old',form='formatted')
read (io_unit,'(A)') str
read (io_unit,'()') 
read (io_unit,'(A)') str
print *,str, "this should be the third line"
close(unit=io_unit,status='keep')
end

and the file named "in":

first line: aaa
second line:bbb
third line: ccc

The second read statment does not eat the second line. The output is:
second line:bbb  this should be the third line
But if we remove the first read statement, the result is correct. IMHO this is 
related with null i/o list and fmt_null. 

This is extracted from 191.fma3d.
