It does not. The debugger starts normally, and after "run" octave starts up 
with its normal prompt.

"demo surf" outputs a bunch of stuff ending with:

gnuplot> if (exists("GPVAL_TERM")) print GPVAL_TERM; else print NaN
                    ^
         line 0: invalid expression

The octave prompt remains; "quit" exits to the debugger and another "quit" 
exits back to the shell prompt.
