echo_executing_commands under 3.6.2 and 3.8.1

[Sigbert Klinke]

Hi,

the call of

  octave -qf < test.m

with test.m:

  echo_executing_commands(4);
  echo_executing_commands()
  magic(5)
  echo_executing_commands(0);

delivers with octave 3.6.2 (debian 7.4):

  + 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);

and under octave 3.8.1 (ubuntu 14.04):

  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

If I call octave from the command line and type in the commands by hand 
then in both versions of octave behave like in 3.6.2.

1.) Bug or feature?
2.) If it is a feature then how can I get the same behaviour in 3.8.1 as 
in 3.6.2? I would like to see the echoed commands.

Thanks in advance
