RE: Added text makes `C-h b' wider than 70 chars

[Drew Adams]

        I've never seen a list of bindings what would not require
        vertical scrolling anyway, so I don't think adding to the
        vertical dimension would do any harm.

    That reasining is not valid.  If the change makes only half as many
    commands fit in one screenful, that is a change for the worse.

I don't see the change doing that, but I could be wrong. In practice, I've
only seen this added to less than a dozen lines.

And I've never seen `C-h b' output that is less than a full screen in
height, as I said. I can't speak for what others see.

Perhaps you mean that even if the window must be scrolled vertically anyway,
this would be unacceptable because it would mean needing to scroll more. If
so, then the question comes down to whether or not there are many such
lines. Yes, if half the lines had this addition, then the vertical scrolling
would be doubled.

Anyway, your "(shadowing)" fix should do the job pretty well.
