Re: [PATCH] Window resizing

[Richard M. Stallman]

Thanks for working on this problem.

    The bug seems to arise because dragging the mode line is done through
    enlarge-window which can sometimes move the top of the window rather than 
the
    bottom.

Perhaps what we need, in order to fix this reliably, is to add a
way to call enlarge-window and say "move only the top or left edge".

      mouse.el seems to have an inappropriate constraint on enlarge-window
    (third arg t window gets larger).

I can't parse that.  Could you explain it less tersely?

The reason for passing t as the third arg is to insist on
moving the bottom edge.  That is surely the right thing for
it to do in some situations.  Why do you think it is wrong?
