bracketed paste on 4.4.20(1)-release

[Sergei Gerasenko]

Hello,

I’m seeing strange behavior in bash on CentOS 8. The version of bash there is 
4.4.20(1). The 4.2.46(2) version on CentOS 7 doesn’t have this problem. The 
versions of readline are 6.2 and 7.0 respectively. The problem is that when 
vi-mode is on and bracketed paste is enabled in .bashrc with:

bind 'set enable-bracketed-paste on’

… pasting while in the INSERT mode will result in: a bell + “(arg: 200)”

I suspect this is because the bracketed paste escape sequence has 200 in it. 
Namely, "ESC [ 200 ~”. Is this a known bug and is there a workaround? The 
readline version on C8 is readline-7.0.

Thanks for any ideas!
  Sergei
