Subject: [PATCH] Pretty print errors using Display instead of Debug
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Until now, error reporting relied on the default behaviour of Rust’s
`Termination` trait which would print a debug representation in case of
an error.
