regarding the above, I stand corrected: it does indeed have effect but only on 
'read -e' (just as the comment states), that bash_event_hook() function isn't 
entered for 'read -p' which to me was surprising, yet no doubt correct(I'm 
guessing).
The code that allows 'read -p' to be interrupted when posixly_correct, must 
then be somewhere else, I shall keep lookin', yet I fear I might not find it :-"
