Describe the bug

• OS and Version: Windows 7
• VS Code Version:
  Version: 1.33.1 (system setup)
  Commit: 51b0b28134d51361cf996d2f0a1c698247aeabd8

  Node.js: 10.2.0
  V8: 6.6.346.32
  OS: Windows_NT x64 6.1.7601
• C/C++ Extension Version:
  Version 0.22.1
• Other extensions you installed (and if the issue persists after disabling them):
• A clear and concise description of what the bug is.
  std::vector<std::set<int> > my_vector;
  is automatically corrected to:
  std::vector<std::set<int>> my_vector;

The latter is illegal (at least before C++ 11) and throws the error:
error: '>>' should be '> >' within a nested template argument list

To Reproduce

1. In a *.cpp file, type this line manually (not copy pasted):
   std::vector<std::set<int> > my_vector;
2. Press enter.

Expected behavior

That the space between > > would not be removed in cases such as this.

Additional context

[sean-mcmanus]

The intended design is to set the clang-format Language flag to Cpp03 for pre-C++11 formatting, such as with a C_Cpp.clang_format_style like
{ BasedOnStyle: LLVM, UseTab: Never, IndentWidth: 4, TabWidth: 4, BreakBeforeBraces: Allman, AllowShortIfStatementsOnASingleLine: false, IndentCaseLabels: false, ColumnLimit: 0, AccessModifierOffset: -4, Standard: Cpp03 }.

However, it would be better for us to have the out-of-box Visual Studio style to automatically use the current C++ language standard, so we'll use this issue to track that.

@elahehrashedi I didn't realize this fix got checked in so it wasn't added to the changelog yet...might rebuild the vsix Monday or just update the release page until 0.28.0-insiders2.
