Details:

I am unsure of where this error originates, pdfmark.tmac, grops, ghostscript,
or ???  Please check the attached image to see where the hotspot actually
appears - it is not on the item.  The vertical distance between the hotspot
and where it should be increases with .pdfhref entry

Please see attachments for test files,
1) seealso.man
2) SAMakefile
3) resulting seealso.pdf

command as invoked by make::>

pdfroff --no-toc -t -p -man -mpdfmark -fP -rLL=5.2i -rLT=5.2i -rD1
-dc_date="`date +'%e %b %Y'`" -dc_year="`date +%Y`" seealso.man > seealso.pdf
cp seealso.pdf ../../html/dflibg/pdf/

[note: everything is really boluxed without --no-toc]
