Follow-up Comment #7, bug #57592 (project groff):

[comment #5 comment #5:]
> And while I'm here I will add that doing the above would be irritating for
`an-old.tmac` at least, which pledges itself to classical troff compatibility
and therefore has matchbox-sized namespace.

Amusingly, my correction comment introduced an even bigger error than the one
I was fixing in the first place.

`an-old.tmac` is _not_ written in classical troff; it deploys many GNU roff
features and uses prodigiously long register names that for all I know cause
buffer overflows in Heirloom troff.  Somewhere my brain knew this, because I
mentioned a couple of them in the groff_man(7) page.

It is `an-ext.tmac` that is written in the compatible dialect.
