New Revision: 172789

URL: http://llvm.org/viewvc/llvm-project?rev=172789&view=rev
Log:
Formatter: After case blocks, "break" goes on the same line as the "}", PR14907.

Before:
switch (foo) {
case a: {
  int a = g();
  h(a);
}
  break;
}

Now:
switch (foo) {
case a: {
  int a = g();
  h(a);
} break;
}
