Well nothing so romantic: I didn't read it 20 years ago; more like some time in the last couple of years. And though I vaguely recall seeing this comment in the context of its code (on GitHub?), I may have well ended up there via a HN comment in a thread much like this, so that wouldn't be surprising. :-)
"I read your Forth code from 20 years ago, please help me understand your comment string" - to the original author.
I am praying this gets resolved. This needs to be on the front page by itself.
