New description:
This is taken from the google notebook bug report page.
{{{
sage: limit(tanh(x),x=0)
x
}}}
On the other hand, this works
{{{
sage: limit(tanh(x),x=0,taylor=True)
0
}}}
It is a bug in Maxima, and is still present in sage-5.0beta8. This beta
apparently has maxima-5.26, the latest released version of Maxima.
----
Update: It has been fixed upstream. It is in maxima-5.27
