OK, the behaviour on my terminal is completely different depending solely on which shell I
use:
s@...aptop ~> bash
s@...aptop:~$ That is plain not true, but depends on the "bracketed paste" mode
Command 'That' not found, did you mean:
command 'phat' from deb phat-utils (1.5-3build2)
command 'chat' from deb ppp (2.4.7-2+4.1ubuntu5.1)
command 'jhat' from deb openjdk-8-jdk-headless (8u382-ga-1~20.04.1)
Try: sudo apt install <deb name>
s@...aptop:~$ of readline which in turn depends on the terminal (emulator) and
bash: syntax error near unexpected token `('
s@...aptop:~$ likely even upon the ncurses library.
likely: command not found
s@...aptop:~$ See bash(1) (Readline Variables, enable-bracketed-paste, default
bash: syntax error near unexpected token `('
s@...aptop:~$ on). Btw Mr. Dickey (ncurses, xterm, vile, etc) has an
bash: syntax error near unexpected token `)'
s@...aptop:~$ fish

See bash(1) (Readline Variables, enable-bracketed-paste, default
on). Btw Mr. Dickey (ncurses, xterm, vile, etc) has an
informative page on this:

Yes, I'm on an older release still, so maybe it has been fixed in the past 3 or so years.
