limit!-((abs(x)-3)/(x-3),x,3); yields -1 instead of 1.
A preliminary analysis shows that the the error occurs with "off usetaylor;", whereas the result is correct with "on usetaylor;".
The reasons behind this is the incorrect power series expansion when using the tps package. Compare:
3 + eps + O(eps )
3 - eps + O(eps )
