Error in display of a continuous map between open intervals #30289
Description
Define a continuous map between two intervals:
sage: R.<t> = RealLine()
sage: I = R.open_interval(0, 2*pi)
sage: J = R.open_interval(2*pi, 6*pi)
sage: h = J.continuous_map(I, ((t-2*pi)/2,), name='h')
Before this ticket, it displays incorrectly:
sage: h.display()
h: (2*pi, 6*pi) --> (0, 2*pi)
t |-->
After this ticket, it displays correctly:
sage: h.display()
h: (2*pi, 6*pi) --> (0, 2*pi)
t |--> t = -pi + 1/2*t
