[seqfan] Re: A marginal observation on some tables of R. H. Hardin

[Ron Hardin]

It's easy to add the %Y lines (done!) to the generating programs but it changes how you look at the line if it's an index of mentions above rather than something you might want to look at as decided by a human.  Either way is okay.  It just changes the use.

The count-against is that you lose the human editor, and so may skip them all because so many are useless.
