user defined error handling

[Matt Flax]

Hi there,

I have been interested in using my own error handlers with octave.

For this purpose, I have changed 'initialize_error_handlers' with my own.
  set_liboctave_error_handler (my_error_handler);
  set_liboctave_warning_handler (my_warning);
  set_liboctave_warning_with_id_handler (my_warning_with_id);

Unfortunately I have found that octave actually do nothing to execute my 
error handlers when errors occur ... it appears that regular error 
handlers like 'error' 'verror' 'error_2' and 'error_1' are executed as 
per usual.


Is there perhaps some way to 'initialize_error_handlers' more 
appropriately ?

thanks
Matt
