yy copies a newline in front of the line about ble.sh HOT 2 CLOSED

That is the correct behavior.

What inserts the newline is not yy, but p. For the linewise range, p pastes the lines after the current line. This is exactly Vim's behavior. I haven't thought about it consciously until now, but after some trials, I feel the current behavior is still natural even in the shell. Though, it's interesting to see some people seem to expect a different behavior.

If you want to paste the line before the current line, you need to use P. Or if you expect p to always behave like P, you might consider rebinding it as ble-bind -m vi_nmap -f p vi_nmap/paste-before.
