Label tie chains in expr with prolated tie chain duration:
abjad> staff = Staff(notetools.make_repeated_notes(4))
abjad> tuplettools.FixedDurationTuplet(Duration(2, 8), staff[:3])
FixedDurationTuplet(1/4, [c'8, c'8, c'8])
abjad> tietools.TieSpanner(staff.leaves[:2])
TieSpanner(c'8, c'8)
abjad> tietools.TieSpanner(staff.leaves[2:])
TieSpanner(c'8, c'8)
abjad> tietools.label_tie_chains_in_expr_with_prolated_tie_chain_duration(staff)
abjad> f(staff)
\new Staff {
