Stabilize pointer after reply-to clicks..

Browse Source 
The reply-to autoscroll was using a flag that was redundant
to suppress_scroll_pointer_update and then updating it prematurely,
which caused the pointer to move when you clicked on a message to
reply to it.  Now the pointer goes to the message you replied to.
