bug#5766: 23.1.94; invisible pointer still highlights text

[Jay Berkenbilt <ejb@ql.org>]

I like the new feature in 23.1.94 of having the mouse pointer turn
invisible when you are typing.  However, if text is set to highlight
when the pointer is over it, this still occurs when the invisible
pointer is over something.  This can be disorienting if you switch
contexts into a buffer that has this.  For example, if you're typing
away and then switch to gnus, info, or any of the other many places
where there is mouse-selectable text, some seemingly random text on the
screen may be highlighted because the invisible cursor is over it.  If
possible, it seems like any behavior triggered by the mouse pointer
being over something should be disabled when the mouse pointer is
invisible.
