Summary: limit(sqrt(x),x,minf) not fully evaluated

Initial Comment:
Maxima returns a noun form, which can be evaluated in a second step:

(%i2) limit(sqrt(x),x,minf);
(%o2) %i*('limit(sqrt(x),x,inf))
(%i3) %,nouns;
(%o3) %i*inf

The limit of sqrt(minf) returns a noun form with a gensymbol:

(%i4) limit(sqrt(minf));
(%o4) %i*('limit(sqrt(?g23883),?g23883,inf))
(%i5) %,nouns;
(%o5) %i*inf

I think the answer infinity is more correct. The answer %i*inf might be correct too. But Maxima can not handle directed infinities.
