Well, i"ll answer my own question. It turns out that MM will
set \*[hd*mark] to have a value like "1.2.3\ \ ", and that
groff doesn't like those escaped spaces.

I fixed it with a hack to get rid of the two escaped spaces, and
while I was at it grabbed a few lessons from the recently
posted pdfmark macros.

        .de HZ
        .       ds hhh \\*[hd*mark]
        .       chop hhh
        .       chop hhh
        .       pdfbookmark "\\*[hhh] \\$3"
        ..
