Follow-up Comment #1:
> There is a missing test after the comment about 'mG'
I don't agree.
an-ext.tmac is not a stand-alone macro file; like mdoc/doc-common, it is meant
only to be sourced by its parent.
> test-nroff -ww -z an-ext.tmac
The foregoing is (1) therefore an invalid experiment and (2) there is no such
thing as "test-nroff" in GNU _roff_.
> .if !r mG
This uses extended _groff_ syntax and is not portable to AT&T/DWB/Solaris
10/Plan 9 _troffs_.
The point of this file is to be portable to such formatters.
_groff_man_(7):
/.../share/groff/1.23.0/tmac/an-ext.tmac
Except for .SB, definitions of macros described above as
extensions are contained in this file; in some cases, they
are simpler versions of definitions appearing in an.tmac,
and are ignored if the formatter is GNU troff. They are
written to be compatible with AT&T troff and permissively
licensed—not copylefted. To reduce the risk of name space
collisions, string and register names begin only with “m”.
We encourage man page authors who are concerned about
portability to legacy Unix systems to copy these
definitions into their pages, and maintainers of troff
implementations or work‐alike systems that format man
pages to re‐use them. ...
An AT&T-compatible formatter will define the `mG` register as zero upon its
first interpolation, which produces intended results.
Rejecting.
