Bash Version: 4.2
Patch Level: 46
Release Status: release

Description:
        when you edit a line from your bash history, history shows the edited 
version, even if you never ran it
        ewriting history is generally considered bad in most contexts, and i 
found this to be counter intuitive and can't think of why anyone would want it 
this way

Repeat-By:
        echo a b^M^P^W^Necho ^Y
        shows echo a and echo b in your history, even though you ran echo a b   
and echo b, never echo a
