Possible bug related to bracketed paste in version 7

[Sergei Gerasenko]

Hello,

It seems that with version 7 of readline this binding doesn't work as expected:

set keymap vi-insert 
"\e[200~": bracketed-paste-begin 

What happens I think is that the \e is interpreted as a literal escape and the 
user is kicked into the vi-command mode. Here’s my understanding of what 
happens then:

1. The 200 (or "[200~”?) is then fed into readline in the vi-command mode.
2. That is interpreted as a numbered-argument command and the user sees “(arg: 
200)” at the beginning of the line.

One workaround I’ve seen is to do this:

set keymap vi-command
"[200~": bracketed-paste-begin

That does help in that the text is pasted without the “(arg: 200)” marker 
appearing. But then if one presses ANY key, a bell is heard and the input is 
ignored. Only when a key is pressed another time, that it’s interpreted.

The system I’m seeing this on is CentOS 8.

Is this a known issue or is it me?

Thanks!
