thanks for all the fixes, much appreciated.

note that if we ship this as documentation, these become the official
examples so they *have* to be correct. How many times have you copied
something from the examples of a library? Not ideal if there's a bug or just
messy code to begin with :)

As for libevdev: just add a link to the documentation, don't add a libevdev
example. libevdev should (and does) provide the examples and you don't want
to ship example code that relies on some other library' API.
