Make the selection able to exist independent of the cursor position, so

that it is not affected by scrolling. If MouseDragEnd1Pane is bound to
the new "stop-selection" command:

    bind -Tcopy-mode MouseDragEnd1Pane stop-selection

A selection made with the mouse will stay as it is after button 1 is
released. (It also works bound to a key.)
