clang-format: Don't bin-pack text-proto-formatted options.

Before:
  repeated double value = 1
      [(aaaaaaa.aaaaaaaaa) = {aaaaaaaaaaaaaaaa: AAAAAAAAAA,
                              bbbbbbb: BBBB, bbbb: BBB}];

After:
  repeated double value = 1
      [(aaaaaaa.aaaaaaaaa) = {aaaaaaaaaaaaaaaa: AAAAAAAAAA,
                              bbbbbbb: BBBB,
                              bbbb: BBB}];

this was a small change.
