main.rs: Error when more than one ref argument is given
Since it doesn't really make sense to take multiple refs, don't allow more than one. We can only diff between two trees, and one is fixed as the workdir. Also learned that to get an exit code from a `system()` call in Perl, you have to shift `$?` by 8 (https://perldoc.perl.org/functions/system.html).
