I read the "BOGUS" comment as referring to the fact that we have to
specially trap structs and unions, instead of simply passing
everything through common_val_print.  I don't think this patch affects
that "bogusness"; it just makes the workaround work better.

(Are there any cases where common_val_print (and thus c_val_print)
prints the "{...}" we need automatically for us?  Or is this code the
sole source of that behavior?)
