Correct doctests with random output

[David Lucas]

I just noticed that I wrote some of the doctests for methods that have a random output the wrong way. A #random markup should be used (see : http://www.sagemath.org/doc/developer/coding_basics.html#special-markup-to-influence-tests )

I am completely perplexed by the example provided in the above link. A hash is definitely not random.

But the sentence after the example makes it clear : "the doctesting framework guarantees the state of the pseudorandom number generators".

I think there is no need to add the # random tag.

Still, may be there is need to fix your doctests.

I can go through that,

Using a preset seed works better.
