Hi Heinz-Jürgen,
Thanks for debugging and submitting a fix for this problem!
Except that it's not really the most appropriate solution; that was
proposed four years ago...
In general, when proposing changes to the groff code base, it's best
to open a bug report ...
...and Bertrand opened a (belated) ticket:
https://savannah.gnu.org/bugs/index.php?55107
which has shown no activity since; (so even open tickets aren't immune
to fading into obscurity).
Regarding the specific change you've proposed, there may be some
resistance to using a grep option that's not part of the POSIX
standard for the command. I'm not sure how widely implemented -a is,
or what equivalent solution might be more portable.
I would go even further ... groff should *not* be calling out to
external tools, such as grep — much less pdfinfo — from within core
code, in a manner which requires use of unsafe mode, *especially* when
core code to achieve the required functionally has been awaiting
integration for a number of years!
