pdf and certain macro expansion

[Kevin Ryde]

In the current debian i386 packaged texinfo 4.3, recent tetex 1.0.2
and 1.0.7, and texinfo.texi 2002-03-26.08, the file foo.texi below
processed with texi2dvi in pdf mode,

        texi2dvi --pdf foo.texi

gives the error below.  DVI mode seems fine, as does makeinfo.

For what it's worth, my intention was a macro which would be like
pxref but let me put a url into html output.  The form shown in
foo.texi would be for non-html, simply ignoring the url argument.
