Comment (by benjaminfjones):
While updating #11143 I ran into the following issue which occurs when the
patches here and the new pynac spkg are installed:
{{{
sage: integral(e^(-x)*log(x+1), x, 0, oo)
...
ValueError: Computation failed since Maxima requested additional
constraints; using the 'assume' command before integral evaluation *may*
help (example of legal syntax is 'as
sume(Infinity>0)', see `assume?` for more details)
Is Infinity positive, negative, or zero?
}}}
It looks like there is something going on with the conversion of `oo` to
`inf` in maxima.
----
Another comment: why are the instances of `Infinity` in the doctest
patches here changed to `infinity`. Isn't the upper case `Infinity` the
"canonical" Sage infinity?
