Interesting. Actually, it seems the splitting into multiple lines happens if
we're in the `struct`, etc. case, but not if this was likely a braced list:
% cat test.cc
int i = int{16} * 1024;
% ./clang-format -style=google -debug test.cc
Args: ./clang-format -style=google -debug test.cc

test.cc: 15:+1:""
int i = int{16}* 1024;
So maybe we can base it off that distinction. I'll try and explore this idea in
the next few days.
