It works without readline, on typical terminal default settings. Login's 
password prompt obviously does /not/ use readline. Nor does cat, where 
you can see the effects very clearly.

Probably readline wants to do special handling; especially in cases 
where line-wrap occurs.

$ stty -a
speed 38400 baud; rows 24; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^H; kill = ^U; eof = ^D; eol = <undef>;
...

The kill setting is the relevant one.
