An empty date element yields extraneous space and comma in the text output (and nroff output). v1 handled this OK, but v2 puts in extra " ,"

(Simply deleting the empty date element isn't a good option b/c the DTD requires it in the reference element.)

XML:

<reference anchor="VARIANTTLDS" target="http://www.icann.org/en/resources/idn/variant-tlds">
   <front><title>IDN Variant TLDs</title>
      <author>
          <organization>ICANN</organization>
      </author>
      <date />
   </front>
</reference>

v2 output:

   [VARIANTTLDS]
              ICANN, "IDN Variant TLDs", ,
              <http://www.icann.org/en/resources/idn/variant-tlds>.

v1 output:

   [VARIANTTLDS] 
              ICANN, "IDN Variant TLDs",
              <http://www.icann.org/en/resources/idn/variant-tlds>.
