Re: Elisp manual omission?

    At this point, I'd be happy with _any_ line, even not a clear one.
    Something like ``let's not document everything'' just doesn't cut it,
    sorry.

I wish I could give you the line that you want, but I can't.  The
criterion is mostly a matter of how often, and how generally,
something is likely to be useful.  But I cannot find the words to
state where the threshold is.  It's a matter of "is this going to be
worth the paper it's printed on?"
