479 Deciding what to mirror to the console wrt to breakpoints
480 and random stops gets messy real fast. E.g., say "s"
481 trips on a breakpoint. We'd clearly want to mirror the
482 event to the console in this case. But what about more
483 complicated cases like "s&; thread n; s&", and one of
484 those steps spawning a new thread, and that thread
485 hitting a breakpoint? It's impossible in general to
486 track whether the thread had any relation to the commands
487 that had been executed. So we just simplify and always
488 mirror breakpoints and random events to the console.
490 Also, CLI execution commands (-interpreter-exec console
491 "next", for example) in async mode have the opposite
492 issue as described in the "then" branch above --
493 normal_stop has already printed frame information to MI
494 uiout, but nothing has printed the same information to
495 the CLI channel. We should print the source line to the
496 console when stepping or other similar commands, iff the
497 step was started by a console command (but not if it was
