[PATCH] clang-format: make alignment after 'return' configurable

[Daniel Jasper]

Hm. If you think this is Java-specific, I might be inclined to gate this based on the Style's Language for now. The problem is that each additional configuration flag has a certain amount of cost, e.g. because:
- Style flags become less discoverable
- Maintenance increases when ensuring that all combinations of flags work as expected
