Align to the new, sane behaviour of the groff_mdoc(7) .Dd macro:

without an argument, use the empty string, and always concatenate
all arguments, no matter their number.
This allows reducing the number of arguments of mandoc_normdate()
and some other simplifications, at the same time polishing some
error messages by adding the name of the macro in question.
