Re: Moving vertical boundaries after C-x 3

[Richard Stallman]

When you click on a mode line to delete "the window", it is clear
which window that is.  The mode line belongs to a window.

When you click on the vertical line, which window gets deleted?  Is it
the one whose scroll bar you're under?  That would be the logical
answer.  But I think it will not be very clear to users, and therefore
I think that it is better not to make this change.
