Comment (by aschilling):

 Hi Dan,

 I think in your commit message, you can delete the two lines
 {{{
 imported patch weyl_characters.patch
 * * *
 }}}

 I ran

 {{{
 sage -coverage weyl_characters.py
 ----------------------------------------------------------------------
 weyl_characters.py
 SCORE weyl_characters.py: 94% (63 of 67)

 Missing doctests:
          * __pow__(self, n):
          * irreducible_character_freudenthal(hwv, L, debug=False):
          * get_branching_rule(Rtype, Stype, rule):
          * __classcall__(cls, parent, prefix=None):


 Possibly wrong (function name doesn't occur in doctests):
          * _repr_(self):
          * product_on_basis(self, a, b):
          * simple_coroots(self):
          * _repr_(self):
          * product_on_basis(self, a, b):
          * _repr_term(self, t):
 }}}
 Since the method {{{__pow__(self, n)}}} is new, I suppose at least this
 method should have a doctest. You can add #indirect doctest behind tests
 that indirectly test the function. Then sage -coverage probably won't
 complain about the possibly wrong functions any longer.

 In the docstring for the method dot_reduce, I think you want the line

 "Auxiliary function for product_on_basis."

 as the first line. Then INPUT: and the - ``a`` ... with the same indent at
 INPUT.
