Comment(by jhpalmieri):
I'm happy with the changes except for the following things: first, there
are some typos and some ways I would reword things, and I've put up a
patch to go on top of "trac_9370-module-elt-repr-suggestions-cs.patch" to
make those changes.
Second, the change in the `print_options` method makes the code simpler,
but it also modifies the behavior, and I'm not sure I like the change. If
we want to keep the change, then we need to modify the documentation. The
change is this: with my original patch, if you set `prefix` but not
`latex_prefix`, then `latex_prefix` would become `prefix` rather than the
default value of "B". With your patch, we have this behavior:
{{{
sage: A = HeckeAlgebraSymmetricGroupT(QQ, 3)
sage: A.an_element()
T[1, 2, 3] + 2*T[1, 3, 2] + 3*T[2, 1, 3]
sage: latex(A.an_element())
B_{[1, 2, 3]} + 2B_{[1, 3, 2]} + 3B_{[2, 1, 3]}
}}}
Ideally, everyone would set latex_prefix when they set prefix, but if they
don't, I think they should default to being the same.
