Re: 'continue' command problem

[Jim Ingham <jingham@apple.com>]

Ah, sorry, I just called the field "commands".  It's done in  
breakpoint.c, in "print_it_typical" (in the Apple sources).

The way I implemented it, I added a *started message to tell the UI  
that we had restarted because of a breakpoint command, as well as a  
^continuing.  I forget exactly why I chose to do it this way, it's  
maybe a little overdetermined.  (Note, we also added a -breakpoint- 
commands" command to set the breakpoint commands...)

Anyway, this looks like:
