Help: lfungenus2(F): returns the Ldata structure attached to the
 L-function attached to the genus-2 curve defined by y^2=F(x)
 or y^2+Q(x)*y=P(x) if F=[P,Q].
 Currently, only odd conductors are supported.
Doc: returns the \kbd{Ldata} structure attached to the $L$ function
 attached to the genus-2 curve defined by $y^{2}=F(x)$ or
 $y^{2}+Q(x)\*y=P(x)$ if $F=[P,Q]$.
 Currently, if the conductor is even, its valuation at $2$ might be incorrect
 (a warning is issued).
