Details:

Seems to come in 3.2.4 since the same script was reported to work ok in 3.2.3
. ATM I have access only to older version:


$> echo "ver(); {1 2 {3 4}}; 'fine'" | octave -q

----------------------------------------------------------------------
ans = fine


on current system


$> echo "ver(); {1 2 {3 4}}; 'fine'" | octave -q || { echo "ver()" | octave
-q; }
parse error:

  syntax error

>>> ver(); {1 2 {3 4}}; 'fine'
                   ^

and on current tip of octave:


$> echo "ver(); {1 2 {3 4}}; 'fine'" | octave3.3 -q || { echo "ver()" |
octave3.3 -q; }
parse error:

  syntax error

>>> ver(); {1 2 {3 4}}; 'fine'
                   ^

Adding , within nested array definition "fixes" the problem. Matlab also
experiences no problem
