New description:
After the patch, Dynkin diagram ascii art is available for reducible
Cartan types.
{{{
sage: DynkinDiagram("F4xA2")
O---O=>=O---O
1 2 3 4
O---O
5 6
F4xA2
sage: CartanType("B2xC2").dynkin_diagram()
O=>=O
1 2
O=<=O
3 4
B2xC2
}}}
The patch {{{trac_6050.patch}}} goes on top of
{{{trac_5502-revised.patch}}} but that has been merged in sage-4.0rc0.
The second patch {{{trac_6050-1.patch}}} corrects a minor misformatting in
Type D extended ascii art.
