Invalid Json

[pvouzis]

I use the "--quiet" flag in order to get a json and them extract the fields from it.

In the following put there is an error printed on the bottom which obviously makes the whole output not a valid json. If the intention of the "--quiet" flag was to output a parsable json, then this format breaks it. One way to deal with this would be to make the error message part of the json and not print it on stderr.

I guess I could also parse just stdout and avoid stderr, but also sometimes the errors need to be parsed.

$> mach --quiet
