Note that single multiline statements can be directly copied for pasting 
by the normal method.

The prompt and separator could be configurable.

A few users have noticed (and complained) that setting sys.ps1 and 
sys.ps2 *in the batch mode user process* has no effect. The Idle doc 
should better explain why this is and should be.  User code should not 
affect the operation of Idle. Idle is separately configured through dialogs.
