I'd like reconsider [the new error output][1] with short exception trace always displayed at top, IMHO it's annoying for common exceptions (there is not real debugging reason, the message is clear enough) such as `Symfony\Component\Console\Exception\*` which have an impact into current CLI applications.

However, I'm proposing display it for unexpected exceptions or if verbosity is enabled:

Note @nicolas-grekas's symfony#21414 (comment) is still covered.
