Can you confirm that the commands

echo start
sleep 1
echo end

have the same effect?  That would make it easier to test on non-arch
systems, and understand the general issue.

And

echo start
true
echo end

does not?

No, it works as it should. Same with true command.
It's just commands that read from the standard input behave that way. (pacman, apt, etc)
1. Create a file named ~/a.sh with content
read -p "Continue (y/n)?" choice
2. chmod +x ~/a.sh
3. emacs -q
4. M-x shell
5. echo start
~/a.sh
echo end

The result is
~ > echo start
~/a.sh
echo end
echo start
start
~ > ~/a.sh
Continue (y/n)?y
y
~ >
