Details:

The attached test.m called from the command line via  "octave -qf < test.m"
results in 3.8.0 & 3.8.1:


  ans =  4
  ans =

     17   24    1    8   15
     23    5    7   14   16
      4    6   13   20   22
     10   12   19   21    3
     11   18   25    2    9 


and in 3.6.4:


  + echo_executing_commands()
  ans =  4
  + magic(5)
  ans =

     17   24    1    8   15
     23    5    7   14   16
      4    6   13   20   22
     10   12   19   21    3
     11   18   25    2    9

  + echo_executing_commands(0); 


If I start octave 3.8.1 and type in the command by hand then I get the same
result as in 3.6.4. 

The problem might be with the function 


void octave_base_reader::do_input_echo (const std::string& input_string)
const


in the file libinterp/corefcn/input.cc .

When typing in the commands within octave the function is called, when calling
"octave -qf < test.m" the function seems not be called.
