It does not `default to on'.  The first place to look is ~/.inputrc or
the file named by the INPUTRC variable.   This is the readline startup
file and probably where the variable is being enabled.

Check the value of the TERM variable and the appropriate termcap
entry.  Readline needs to be able to move the cursor up and down and
likes to know whether the terminal supports autowrap.  If your
terminal type is unknown or the corresponding termcap entry is
incomplete or incorrect, readline doesn't know how to move the cursor
and forces horizontal scrolling.  The one you need to make sure about
is the `up' capability.
