This may not be exactly what you want, but it may help.  If you are
putting all of your commands in a file to execute, you can do this,

  octave --echo-commands script-file

and Octave will print each command as it is executed, followed by the
output that is produced.  The commands are preceded by the value of
the built-in variable PS4 (the default is "+ ").  If you would prefer
some other string prefix, you can change the value of PS4 at the top
of your script.

(This is somewhat like running `/bin/sh -xv'.)

Version 1.1.1 does not have a way to turn command echoing on or off
once Octave is started.  That should probably change for 1.2...

: 2)    The problem here is that I can't get 'diary' to work when the
: subsequent commands come from a command file.

This is also the way Matlab appears to work.
