#8963: Make tableau row_stabilizer return group of perms involving all elements
of
the tableau
-------------------------------+--------------------------------------------

-------------------------------+--------------------------------------------
The row_stabilizer method of a tableau ignores elements of the tableau
which are alone in their row, and this can cause problems. For example,
{{{
sage: t = Tableau([[1,2],[3]])
sage: rs = t.row_stabilizer()
sage: PermutationGroupElement([(1,2),(3,)]) in rs
False
sage: rs.one().list()
[1, 2]
}}}
The expected output is "True" and "[1, 2, 3]".
I will attach a patch fixing this in a few minutes.
