return value of octave from command line in case of memory error

[Luca Citi]

Hello,
first of all thank you for developing octave which is a great tool.
My problem...
I have noticed that the return value of octave when running non-interactive is 0
even when octave aborts due to insufficient memory. See below. As the return
value is 1 if there is a different type of error (e.g., undefined function
name), I think it should return non-zero even when the reason for the error is
an unsuccessful allocation. To fix this issue it is sufficient to add "     
error_state = 2;" around line 411 (inside the catch bad_alloc) and line 479 of
octave.cc (version 3.2.4) .
Thanks,
Luca
