This is really a problem Mathematica seems not to be able to solve. The
problem is that it fails to calculate the limit

inf(1-erf(inf)) for inf->Infinity.

Doing this from hand with help of de L'Hospital's rule gives clearly 0.
Although I used Analytic->True within the Limit-command it didn't apply
this rule.
