Hello Bart,

I have a multi-line prompt.

When I have an empty prompt and I press Ctrl-C, I get the next prompt.
But, when I have the list-choices active and I press Ctrl-C, the line
above the command is disappearing.

For example, this is the behavior when zle list-choices is not active
and I press Ctrl-C:

- (0:i:/tmp/zsh-build)  -  -  -  -  -  -  -
l
- (0:i:/tmp/zsh-build)  -  -  -  -  -  -  -

This is the behavior, when zle list-choices is active and I press
Ctrl-C:

- (0:i:/tmp/zsh-build)  -  -  -  -  -  -  -
l
ls
- (0:i:/tmp/zsh-build)  -  -  -  -  -  -  -

It should have been:

- (0:i:/tmp/zsh-build)  -  -  -  -  -  -  -
l
- (0:i:/tmp/zsh-build)  -  -  -  -  -  -  -
ls
- (0:i:/tmp/zsh-build)  -  -  -  -  -  -  -


When I "git bisect" zsh, I found that this:

691547cda60f0512c645e80246292936e660f326 is the first bad commit

    33563: Completion/Base/Core/_main_complete, Src/Zle/complist.c: fix thinko in status message for INT/QUIT signals; check errflag in output loops

    Two semi-related patches for keyboard interrupt handling in completion,
    most importantly so that unexpectedly long completion listings can be
    interrupted.

Any kind comments, please?

Thanks
