You lost me, I'm afraid. Why is that a violation, and which layer
should the knowledge belong in? Or are you suggesting mr could
*automatically* detect whether an arbitrary action is interactive or
not? I can't imagine how this would be possible, short of some ugly
hack involving Expect.

No, because it's optional; it just provides these benefits
- mr will know it needs to complain when the user uses -q and/or -j with
- When mr knows it's running a non-interactive action, it can capture
STDOUT/STDERR, and then if the user requests it, omit sections of the
output corresponding to repo actions which produced no output.
To me it looks like a simple and non-intrusive way of solving two
problems in one go. Having said that, if there's a better solution,
I'd be delighted to hear about it, and even implement it!
