The code before
CB-5181 / b675ee35d5b92f5b997a834d4e6575e1edc14ef3 didn't really look before it leapt, which meant that a platform with only a cordova/version.bat and no cordova/version would magically work.
While I'm not sure of any Windows only platforms, it doesn't seem unreasonable.
A quick check confirms that in fact windows8 doesn't have this file.
