commit e0d2a26757e69d479386eccc58ee0efa3fbd143e
Author: G. Branden Robinson <[email protected]>

[gropdf]: Make pdfmom disclose version of groff.
* src/devices/gropdf/pdfmom.pl: When handling `-v`/`--version` option,
run "groff" with the `--version` option as well, as our other wrapper
programs nroff(1) and groff(1) do. This makes it easy to see if the
versions of the various programs in the pipeline are askew.
Fixes <https://savannah.gnu.org/bugs/?67618>. Problem appears to date
back to pdfmom's birth in commit f2a501fff5, 31 August 2012.
