It's bracketed paste, which is enabled by default in bash-5.1-rc1. The
escape sequence that readline sends to the terminal to turn off bracketed
paste ends with a carriage return, to avoid confusing the Linux terminal
driver about the physical location of the cursor, so the cursor ends up at
column 0. If readline has seen EOF, the shell is going to print something
one way or another, and that text will overwrite what is on the current
screen line. Readline outputs a newline to compensate.
