Incorrectly indents pasted code when preceded by existing try/catch blocks

When pasting a piece of C++ into the editor, the resulting paste is incorrectly indented if the current file already contains code using some uses of try/catch blocks.

When it occurs varies, but the following case seems to cause it each time:

• Create a file with the content:

  struct X
  {
      void fn()
      try
      {
      }
      catch (...)
      {
      }
  
      void fn2()
      try
      {
      }
      catch (...)
      {
      }
  
      int x;
  };
  
  

• Then paste some valid code after the above.

The two try/catch blocks AND the member variable seem to be required.
