Readline 8.1 by default enables bracketed paste (by having introduced a new configure option, --enable-bracketed-paste-default, which is on by default).
This seems like quite the behaviour change to chuck on unsuspecting people, so I'm suggesting to add --disable-bracketed-paste-default to CONFIGURE_ARGS.
On the off chance I am not the only one ticked off by this, adding 'set enable-bracketed-paste off' is the way to turn it off[*]. Since now there is a(nother) publicly documented way people may find, feel free to WONTFIX.

Can I request that if the proposed option:
'set enable-bracketed-paste off'
is incorporated. That it be on by DEFAULT?
I too feel this is an astonishment. That can
cause too much unexpected outcome for no
*immediately* apparent reason.
