[RFC PATCH wayland 3/3] contributing: reformat code examples

[Pekka Paalanen]

From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>

Before, the code examples looked good in the file, but a hard tab was
rendered as 4 spaces by Gitlab.

Now, Gitlab renders the code examples like they should look, with 8-wide
tabs, but the file looks awful.

Is it better with or without this patch?
