New description:
{{{
sage: mathematica(1)
}}}
hangs indefinitely if `Mathematica` is not installed.
The reason is that internally the script `$SAGE_LOCAL/bin/math-readline`
is called by `Expect()`, and the latter hangs. This script should check
whether the `math` command has finished.

Comment:
This is really the wrong fix.
