bug#24431: 25.1.50; Wrong indentation in C++ mode when calling constructors with braces

[Matthias Meulien]

Just type the following lines in a buffer with c++-mode enabled:

struct line_t;
struct point_t;

void set_line(line_t);

set_line(line_t(point_t(0.4, 0.2),
                point_t(0.2, 0.5)));

set_line(line_t{point_t{0.4, 0.2},
      point_t{0.2, 0.5}}); // wrong identation
