Concatenate all include statements into one.

Can we not do this please? It makes it a bit more annoying to tweak the settings script when using Gradle's composite build feature, where you need to change include directives to includeBuild and back for example.

Unless there's some advantage to doing this I'm not aware of?

[chao2zhang]

The only advantage is the visual appearance - I have reverted the change.
