Comment (by kedlaya):

 It appears that this format works:
 {{{
 sage: K.S_unit_group(S=S) == SUK
 True
 }}}
 so a simpler alternative would be to edit the docstring for `K.unit_group`
 to refer to `K.S_unit_group`.

 Aside: confusingly the argument `S` is not positional:
 {{{
 sage: K.S_unit_group(S) == SUK
 False
 sage: K.S_unit_group(S) == K.unit_group() # S is ignored!
 True
 }}}
