* transfer.c (read_sf_internal): Remove bogus code to detect EOR.
(read_block_form): For internal units, generate EOR if no more
bytes left in unit and we are trying to read with ADVANCE='NO'.

* gfortran.dg/read_3.f90: New test.

Simplified test (the infamous IO of numerical values with the '(A)' format)

  PROGRAMGFORTRAN_710_IO_BUG
  CHARACTER  STR*4
  INTEGER*4  I4
  str =''
  i = 256
  write(str,fmt='(A)') I
  print *, ichar(str(1:1)), ichar(str(2:2)), ichar(str(3:3)),
ichar(str(4:4))
  READ ( UNIT=STR(1:4), FMT='(A)' ) I4
  WRITE ( 6, * ) ' I4= ', I4
  END  PROGRAM  GFORTRAN_710_IO_BUG 

Likely caused by r246478 (pr78881).
