This addresses a bug that was reported here:
http://groups.google.com/group/sage-combinat-devel/msg/252fd7fa0e297214
The {{{__call__}}} method of a Weyl Character ring, when
{{{style="coroots"}}} is specified, tries to interpret the arguments as
the coroots of a weight; that weight
is then the actual argument. However this is not appropriate if the
argument is
not a tuple. Therefore this should be tested.
The patch implements the test.
