* Don't force immediate interactive without -i Sometimes we might want to use a reverse prompt but we want to let the model generate tokens right after the initial prompt. So we don't force user input mode if the -i flag wasn't specified and instead let it run until we encounter the reverse prompt. This gives use some more flexibility, since it doesn't force the user to enter a newline if they want to let the model generate text right after the initial prompt and only be asked for input if the reverse prompt is encountered. The `--interactive-first` flag is reintroduced to force the old behavior. `-r` behaves like `-i` plus introduces a reverse prompt (it can be specified more than once). * Update help output. --------- Co-authored-by: Johnman <tjohnman@github>
