readline: edit-and-execute-command

[josh]

anybody know why "edit-and-execute-command" doesn't work in python's readline?  
it doesn't even show up in a dump of readline functions:                        
                                                                                
$ cat fc_test                                                                   
C-p: dump-functions                                                             
C-e: edit-and-execute-command                                                   
$                                                                               
$ python

--- import readline                                                             
--- readline.read_init_file('fc_test')                                          
                                                                                
if you hit control p, and you won't see 'edit-and-execute-command'              
listed at all, though you will when you run "INPUTRC=fc_test bash"

thanks in advance
