No idea, which is a bit distressing. That code seems to have come in
between 6.7 and 7.0, and I can't find a git copy of that cvs history
anywhere (and the cvs services are long since shut down). Thankfully I
think I've found the old cvsroot on kemper, I'll get that imported.

That certainly would be a less icky solution though, will send an update.
