+ Breakpoint hits should always be mirrored to a console. Deciding
+ what to mirror to a console wrt to breakpoints and random stops
+ gets messy real fast. E.g., say "s" trips on a breakpoint. We'd
+ clearly want to mirror the event to the console in this case. But
+ what about more complicated cases like "s&; thread n; s&", and one
+ of those steps spawning a new thread, and that thread hitting a
+ breakpoint? It's impossible in general to track whether the thread
+ had any relation to the commands that had been executed. So we
+ just simplify and always mirror breakpoints and random events to
+ all consoles.
+
+ OTOH, we should print the source line to the console when stepping
+ or other similar commands, iff the step was started by that console
+ (or in MI's case, by a console command), but not if it was started
+ with MI's -exec-step or similar. */
