It's meant for code to react to changes in the *buffer*, I think (take with a heavy dose of salt, because I could never really understand the design). I suspect that `comint-preoutput-filter-functions` is closer to what you need/want. > I expect the `comint-output-filter-functions' to be called on "hello" > line.

I suspect that those "" actually aren't called asynchronously in response to process output (like the "> " prompts), but rather they're called synchronously directly from `comint-send-input` (not sure why we do that either).
