Remove useless indent information from Buffer

[GuillaumeGomez]

First real PR for this project. :)

[Kijewski]

Good call! Maybe we can later add a prettyprint feature to indent the generated code using prettyplease, but I think that's very low on my TODO list.

With this change Buffer::writeln is infallible. Do you want to remove the Result type result?

[GuillaumeGomez]

Good call, let's remove it. :)

[GuillaumeGomez]

Done!

[Kijewski]

Nice! Much easier to read.

[GuillaumeGomez]

I'll wait for you to merge this to ensure I correctly set up the team settings.

[Kijewski]

Thanks! I have a "merge" button now, but I don't have the privileges to add hooks.

[GuillaumeGomez]

Let me fix that. :)
