Hi list, I'm Paolo the zsh maintainer for openSUSE and SUSE Linux
Enterprise distributions.
We were reported by a customer, that zsh fails to re-enter a command on
the right side of a pipe when command is suspended and the program combo
is defined in a function.
To make sure no changes from downstream introduced this bug, I
replicated using a vanilla zsh version 5.9 downloaded from zsh.org
mirror.
Since the problem is still present, I wrote to you to fix it upstream.
% zsh -f
% fc -l 1 -1 2>&1|less +G #enter less without using a function
^Z #suspend less
zsh: done fc -l 1 -1 2>&1 |
zsh: suspended less +G
% fg #zsh re-enters less properly
: q
[1] - done fc -l 1 -1 2>&1 |
continued less +G
% h(){ fc -l 1 -1 2>&1|less +G;}
% h #enter less in a function
^Z #suspend less
zsh: done fc -l 1 -1 2>&1 |
zsh: suspended
% fg #zsh fails to re-enter less
[1] + done fc -l 1 -1 2>&1 |
continued
zsh: done fc -l 1 -1 2>&1 |
zsh: suspended (tty output)
zsh: done fc -l 1 -1 2>&1 |
zsh: suspended (tty output)

Can you please acknowledge the issue and give me a link to backtrack and
follow fix progress in our systems?
Thank you so much
Paolo
