[with-patch] 2.8.7-alpha0: doctest failure in const.tex

[cwitty]

There are three failures, but the last two are direct consequences of the first one:

File "const.py", line 749:
    sage: vals = E.Lseries_values_along_line(1-I, 1+10*I, 100) # critical line
Exception raised:
    Traceback (most recent call last):

      File "<doctest __main__.example_22[1]>", line 1, in <module>
        vals = E.Lseries_values_along_line(Integer(1)-I, Integer(1)+Integer(10)*
I, Integer(100)) # critical line###line 749:
    sage: vals = E.Lseries_values_along_line(1-I, 1+10*I, 100) # critical line
    AttributeError: 'EllipticCurve_rational_field' object has no attribute 'Lser
ies_values_along_line'

[cwitty]

This function was in 2.8.6 but is no longer in 2.8.7. Was it deliberately removed?

[was]

This was caused by David Roe's refactoring of the ell_rational_field command. Now one does L = E.Lseries(), and there is a method

L.values_along_line(...)
