This is more than cosmetic, it's also highly usable. The presence or absence of the "ok" message allows us to know whether the command aborted. Previously, the "> " prompt appeared when the system expected a prompt in the INTERPRET context, whether the previous command aborted or not. Also, this allows us to get rid of that ugly FLAGS global variable.
