Aha, Roxen.

Apparently it does the + --> space conversion itself, which Apache (and
other web servers to my knowledge) do not do. I believe that could be
characterized as a bug in Roxen; it is not following common CGI practice
of setting QUERY_STRING to exactly what was passed in the URL.

It would be pretty easy to set up a capability in Vend::Server that
looks for MV_ROXEN and re-translates, or better yet use tlink.pl
and do the translation there.
