clang-format version 5.0.0 (trunk 302580)

With #if/else/endif, clang-format eats the space (' ') character between the closing paren
of an initializer in a constructor's initialization list and the open brace for the function body:

```
LoooooooooooooooooooooooongClassName::LoooooooooooooooooooooooongClassName()
    : some_silly_long_named_data_member_(0),
#if defined(FOO)
      another_silly_long_named_data_member_(1) {
#else
      another_silly_long_named_data_member_(2) {
#endif
}

LoooooooooooooooooooooooongClassName::~LoooooooooooooooooooooooongClassName()
```

becomes

```
LoooooooooooooooooooooooongClassName::LoooooooooooooooooooooooongClassName()
    : some_silly_long_named_data_member_(0),
#if defined(FOO)
      another_silly_long_named_data_member_(1) {
#else
      another_silly_long_named_data_member_(2){
#endif
}

LoooooooooooooooooooooooongClassName::~LoooooooooooooooooooooooongClassName()
```

This example doesn't repro if you remove the destructor or if you add a statement to the constructor body.
