When writing C++ code with nested templates, putting two (or more) closing
angle braces together causes the font-lock, show-paren-mode and indentation
to break.  Positioning point on any of the closing parentheses fails to
show the matching opening brace which makes template meta-programs
difficult to read.  Any nested templates will cause this.  The following is
a simple example showing the 2 cases:


template <typename T = std::vector<int>>
  struct foo    // Indentation broken here...
  {
  };


int main()
{
  std::vector<std::vector<int>> vv_int; // Font-lock broken here...

  return 0;
}

This appears to have been fixed in 25.1.
