starange "limit" behaviour



Hi all!

Maxima seems to be unable to calculate the following limit with the "limit"
function

limit(7^n/8^n,n,inf);

and returns the limit unevaluated.

If I use the "tlimit" function I get the correct result

limit(7^n/8^n,n,inf);

0

but if the same function is used on the following limit, an incorrect answer
is returned

tlimit(7^(n^2)/8^n,n,inf)

minf

Is this a bug?
