Option for clang-format to remove empty lines in wrapped function call lines

If I have a function call like the following:
```
ALongFuctionNameToBeCalledHere(some_parameter_one_here,

another_long_name_here_so_wrapping_occurs);
```

I'd like the empty line to be removed by clang-format. `RemoveEmptyLinesInUnwrappedLines` seems close to what I'm looking for, but presumably doesn't have an effect because this is not an unwrapped line IIUC.

Start by tracing clang-format's handling of RemoveEmptyLinesInUnwrappedLines and compare it with the wrapped function-call example in the issue. Done means providing an option that removes the empty line in that wrapped call without changing other formatting behavior; the issue names no file or test path, so those must be located first.
