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.
