Non-JSON error message are not displayed #102
Description
fixit only accepts message from cargo check that are in JSON form. So messages/errors from things like ICE are ignored and not displayed.
I don't think we could simply display the non-JSON message like cargo does here since we would also have to exclude the "Checking" and "Compiling" message from cargo and display the rest. Is there any way we could make cargo not give those messages?
