Describe the bug

"EOF in multi-line statement" error is shown to the user as the raw tuple it was returned as, rather than in a nicely formatted message.

To Reproduce

For example:

1. Take this (invalid) file:

print(

2. Run Black on it with no arguments
3. See a message with the EOF error being shown as a raw tuple representation:

error: cannot format test

Good evening!
This is a feature request (AFAIKT there's no configuration option or duplicate issue for this).

In many cases where nightly rustfmt is applied by CI in public repositories, users will often run cargo fmt themselves directly or through their editor causing warnings arising from using the stable rustfmt where the nightly is required. E.g.:

$ cargo fmt
