CLI not working on Windows

The CLI is not working for me on Windows, and the issue seems to be with this code:

https://github.com/avajs/ava/blob/f9fe8f242dd58d02ab1110f677e82172652d9d3d/cli.js#L11-L15

if (localCLI && localCLI !== __filename) {
    debug('Using local install of AVA');
    require(localCLI);
    return;
}

The problem is with the use of !== to compare localCLI and __filename. In my case, the two variables hold the following values:

localCLI: c:\workspace\...\node_modules\ava\cli.js __filename: C:\workspace\...\node_modules\ava\cli.js

As you can see, the drive letter c: is lowercase in localCLI and uppercase in __filename, thus failing the !== check.

Using !== to compare paths doesn’t seem to be a particularly good idea since there are numerous different ways the exact same path can be encoded. Not sure what the best practice is for comparing paths in node.js is. Perhaps path.relative() could be used?

Although yes, path.relative would be better.

path.relative(localCLI, __filename) !== ''
