that doesn't give credit to the observation that there is an opportunity 
cost to not doing it automatically. it is much easier to imagine that a 
scripting user simply didn't consider the possibility of an interactive 
cancellation than that they really meant to ignore it. therefore, the 
status quo is very likely more harmful than the fallout of starting to 
more aggressively report the situation.

yeah, i've considered that as well.
i think that on the exit status side my solution is adequate - it 
reports in a sufficiently distinctive way that something didn't go quite 
as probably expected.

going further, i'm considering producing a mapping from sha1s to 
message-ids (which i'd persist for automatic chaining of re-rolls). this 
would provide the fine-grained reporting as a side effect.
