But from the prompt (and in the completion menu), SIGQUIT doesn't kill
zsh. This is not consistent.

Well, I initially did SIGQUIT because SIGINT didn't do anything.

Moreover, why does

  zstyle ':completion:*' menu select=long

make the completion so slow?

And shouldn't the output be limited to the screen, like with a pager?

Except that I didn't see it because I expected something else.
[Tab][Tab] normally gives the first completion with my settings,
and that's why I typed that so fast. The issue is that [Tab]
*also* has the effect to answer the question as "yes".
