Use of this has never been documented and the code was
dead for a long while now.

Nobody has spoken up so far "I REALLY NEED THIS!!", and if you say
it hasn't worked anyway, out it goes... less code, less arguments,
less variables...

I have only skimmed the code change and did a quick test build on
FreeBSD.

Your patch has been applied to the master branch.
