typo in g.automorphism_group documentation, for g a graph; also partition parameter isn't tested anywhere in the docstring

[williamstein]

There is a typo in the docstring for the graph automorphism function:

``translation`` - if True, then output includes a a
           dictionary translating from keys == vertices to entries == elements
           of 1,2,...,n (since permutation groups can currently only act on
           positive integers).

Notice that it says "includes a a" (a appears twice).

Also, the doctests in that docstring do not test the partition parameter at all, and it seems to me that would be a very important parameter to illustrate, especially given that the docstring starts {{{
Returns the largest subgroup of the automorphism group of the
(di)graph whose orbit partition is finer than the partition given.
}}}
which suggests that the most important thing the reader should know is that the automorphism_group computes something associated to a partition.
