Follow-up Comment #2:

Thanks, Deri.  I had a senior moment.

The bug was true of groff 1.22.4, which is no longer the current release, and
which I inadvertently tested (juggling 3 versions of groff in my build
environment).

It does not affect the version of gropdf in groff 1.23.0.

But it _does_ affect pdfmom, which seems unaware of the option and reads from
standard input and calls groff.


$ ./pdfmom --version
GNU pdfmom (groff) version 1.23.0.138-38f96
$ echo | ./pdfmom --help
usage: groff [-abceghijklpstvzCEGNRSUVXZ] [-dcs] [-ffam] [-mname] [-nnum]
       [-olist] [-rcn] [-wname] [-Darg] [-Fdir] [-Idir] [-Karg] [-Larg]
       [-Mdir] [-Parg] [-Tdev] [-Wname] [files...]

-a      produce ASCII description of output
-b      print backtraces with errors or warnings
-c      disable color output

-Fdir   search dir for device directories
-Idir   search dir for soelim, troff, and grops.  Implies -s
-Karg   use arg as input encoding.  Implies -k
-Larg   pass arg to the spooler
-Mdir   search dir for macro files
-N      don't allow newlines within eqn delimiters
-Parg   pass arg to the postprocessor
-S      enable safer mode (the default)
-Tdev   use device dev
-U      enable unsafe mode
-V      print commands on stdout instead of running them
-Wname  inhibit warning name
-X      use X11 previewer rather than usual postprocessor
-Z      don't postprocess


The foregoing is groff 1.22.4's usage message, because that's what's in the
$PATH.

If this is fixed in your branch and you're happy with it, you can set the
status to "Ready for Merge" and "Planned Release" to "1.24.0".
