Changed printing of structured arrays does not extend to array scalars #8172

In #8160, the printing of structured arrays was changed to ensure that elements could be formatted with the appropriate print functions. While investigating the resulting test failures for astropy (astropy/astropy#5419), I noticed that the behaviour has changed only for structured arrays, not for scalar structured elements:

In [6]: np.array([(1., 2.1234567890123456789, 3.)], dtype=('f8,f8,f8'))
Out[6]: 
array([( 1.,  2.12345679,  3.)], 
      dtype=[('f0', '<f8'), ('f1', '<f8'), ('f2', '<f8')])

In [7]: np.array((1., 2.1234567890123456789, 3.), dtype=('f8,f8,f8'))
Out[7]: 
array((1.0, 2.1234567890123457, 3.0), 
      dtype=[('f0', '<f8'), ('f1', '<f8'), ('f2', '<f8')])

Would it be possible for the code to work for scalars too?
