Re: not too happy with Emacs 21 vertical-line dragging when scrollbars present

[Richard Stallman]

    That's not correct.  It is easy to put the cursor on that tiny line!  

    The code uses a relaxed check so that if the mouse is within ONE
    COLUMN on either side of the line, the cursor changes to the <-> drag
    cursor.  So there is already a virtual block area there which is TWO
    COLUMS wide there.

I see what you mean.  Yes, that is not hard to use.  But we should
document it.

Also, the mouse cursor changes to various other shapes as I drag
the border sideways.  I think that's a bug--could someone fix it
to remain the double-pointed horizontal arrow while dragging
left and right?
