Cool, I guess "go" more or less matches gdb's "continue" then,

I think that's it, hence getting it to at least step to make progress in this patch. Dexter is still vulnerable to stepping through all of printf, but at least it'll make progress and not hang forever this way.

(It's been a while since I did battle with COM, fixing dbgengs free-running is making its way slowly up my todo list).
