Big change to IDLE Shell

3.10.0b1 is due to be released next Monday.  The big change for IDLE is 
in the Shell.  The first line of entered statement will line up with 
continuation lines and indents will be spaces instead of tabs.  The 
'>>>' prompt will be either above on a line by itself or to the left in 
a Shell sidebar. This release will be missing somethings and may 
otherwise have bugs.  We want to get user testing and feedback 
([email protected]) before the 3.10.0 release and before backporting 
to 3.9 (maybe in late June).  The last maintenance release of 3.8 is 
also next Monday, so it will never get this patch.
