🐛 Delta crash on Windows when using as stand-alone diff tool

[frifix]

For me delta version 0.4.3 crash on Windows 10 when I compare two files with command: delta file_1 file_2
Here is a backtrace:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "Nie można odnaleźć określonego pliku." }', src/main.rs:117:37

After installing difftools on Windows it works. However I don't know if the crash is an intended behavior in this situation.

Thank you, yes I think we can handle this a bit more gracefully!
