If readline-like support is available on the system, it's used.
However, it's apparently only readline-like. For example, on Mac OS
X, the BSD-licensed libedit readline emulation is used by default, it
appears. I wouldn't expect full functionality there.
On GNU/Linux systems, as I wrote, True GNU readline is used. Why this
particular function isn't bound or doesn't work right, I don't know
offhand. It is apparently a bug (my Python sources are from April,
but I can't see why this would change), since the sources say
(ll. 927-931 of Modules/readline.c):
/* Initialize (allows .inputrc to override)
* XXX: A bug in the readline-2.2 library causes a memory leak
* inside this function. Nothing we can do about it.
but even adding a binding to .inputrc doesn't work for me (Gentoo Linux).
are related; I don't know whether it's worth filing an additional bug
as I suspect it will get fixed in passing if 8492 is fixed.
