Thanks Christopher! I agree, if it is possible to have quotation marks around the binary in `core.editor`, then we should support that. Looking at your patch, what do you think about doing something perhaps a bit simpler than a regular expression:

var parts = editor.split(" ");
if (parts.length > 0) {
    var binary = parts[0];
    // Binary might be wrapped in quotes on Windows
    if (binary.startsWith(""") && binary.endsWith(""")) {
        parts[0] = binary.substring(1, binary.length() - 1);
    }
}
var pb = new ProcessBuilder(parts);
