       The following test used to read test="$ischunk != 0 and $fn != ''"
       I've removed the ischunk part of the test so that href.to.uri and
       href.from.uri will be fully qualified even if the source or target
       isn't a chunk. I *think* that if $fn != '' then it's appropriate
       to put the directory on the front, even if the element isn't a
       chunk. I could be wrong. -->
