Follow-up Comment #5, bug #64061 (project groff):
[https://lists.gnu.org/archive/html/groff/2023-04/msg00196.html As discussed
on the list, there are a few tricks available to us.]
1. Run pdfinfo twice and scrape out a different datum on each pass. I fear
this would give up more than was gained by eliminating grep from the
pipeline.
2. Perform a sed stunt involving the hold space.
3. Use groff's `\R` escape sequence to sneak two register assignments onto the
same input line.
Here's an illustration of the last.

This works for me on Solaris 11 (running my "fake-pdfinfo" output generator
instead of the real thing, which isn't installed).
Dave, can you give this a crack on your Mac OS X 10.11.6 host?
