Repeat list l to nonnegative integer length from start defaulting to 0.
abjad> l = range(5)
abjad> listtools.repeat_list_to_length(l, 11)
[0, 1, 2, 3, 4, 0, 1, 2, 3, 4, 0]
When length < len(l) return l[:length].
abjad> l = range(5)
abjad> listtools.repeat_list_to_length(l, 3)
[0, 1, 2]
When length = 0 return an empty list.
abjad> l = range(5)
abjad> listtools.repeat_list_to_length(l, 0)
[ ]
Read optional integer start modulo the len(l).
abjad> l = range(5)
abjad> listtools.repeat_list_to_length(l, 10, 2)
[2, 3, 4, 0, 1, 2, 3, 4, 0, 1]
abjad> listtools.repeat_list_to_length(range(5), 10, -99)
[1, 2, 3, 4, 0, 1, 2, 3, 4, 0]
abjad> listtools.repeat_list_to_length(range(5), 10, 99)
[4, 0, 1, 2, 3, 4, 0, 1, 2, 3]
Raise TypeError when l is not a list:
abjad> listtools.repeat_list_to_length('foo', 10)
TypeError
