If a comparison on the length of a sequence fails, the sequence is truncated in the failure explanation regardless of the verbosity setting.

Example script:

def test_list():
    l = list(range(50))
    assert l == []

def test_list_len():
    l = list(range(50))
    assert len(l) == 49

def test_dict():
    d = dict(zip(range(50), range(50)))
    assert d == {}

def test_dict_len():
    d = dict(zip(range(50), range(50)))
    assert len(d) == 49

Why are the sequences always truncated in the explanations of the length comparison failures, regardless of verbosity?
