gfortran formatted read incorrectly reads beyond end of record when
record length is < io,format length.

Demo:
ian@ian:~/source/test> cat ftest.f95
program ftest
  integer i
  character*1 b(10)

  open (77, file='input_file')
  read (77, '(10A1)') b
  print *, b
end program ftest

ian@ian:~/source/test> cat input_file
Line 1
Line 2
Line 3
Line 4

ian@ian:~/source/test> gfortran -v
Using built-in specs.
Configured with: ../gcc/configure --enable-languages=c,f95
--prefix=/usr/work/2005020/irun
Thread model: posix
gcc version 4.0.0 20050120 (experimental)

ian@ian:~/source/test> gfortran -o ftest ftest.f95
ian@ian:~/source/test> ./ftest

This looks promising.

I'll do a full check later.

The patch does not handle advance="NO" correctly.

I'll need to do something else.

Replying to myself here...

After having thought of this, I think the patch should go in
because it fixes a g77 regression, and advance= isn't among the
things that g77 supports.

Thomas
