Use indentation to increase readability
Granted, this style is definitely not common, but for the short utility-functions of this program it's just the right choice. This provides great flexibility, such that in the long run, it will be possible to also share code between the OS-implementations. This also keeps the state-keeping at a minimum and makes it clearer which functions are implemented on which OS without having to jiggle around with too many files in the process.
