weird less(1) CTRL-Z behaviour

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I've been using the following shell function for ages:

dir() { ls -al "$@" | less; }

On -current (9.99.100 kernel from Oct 9, Userland from Sep 21, zsh
from May), when I CTRL-Z the less(1) and then want to go back in, it
doesn't work and I see the following:

> dir
zsh: done       ls -al "$@" | 
zsh: suspended
> fg
[1]  + done       ls -al "$@" | 
       continued  
zsh: done                    ls -al "$@" | 
zsh: suspended (tty output)  
zsh: done                    ls -al "$@" | 
zsh: suspended (tty output)  

That happens every time I try to 'fg' it.

This was working fine not so long ago, but I don't remember exactly
when it started happening.
