The intention is to put arguments into one line if they fit but only in the 
same line as last character of a receiver expression, e.g.:
```
[[object block:^{
  return 42;
}] aa:42 bb:42];
```
instead of
```
[[object block:^{
  return 42;
}] aa:42
   bb:42];
```
but not
```
[[obj a:42]
    a:42 b:42];
```

I think it gets a little bit too complicated for no reason. Let me revert 
D46879 and rebase this change.
