Mostly the second one, mixed with the fact that nobody's requested
this particular feature before.  Readline is very extensible; bash
adds quite a lot to the basic framework -- look at all the code in
bashline.c.  If you'd like to take a crack at writing a bindable
readline command to do what you want, I'd certainly look at it for a
future version.  (You'll probably get to it before I would.)
