Hello Peter,

when emacs is wrapped inside function,
then emacs is dead when:

^Z
bg

Does not happen when emacs called w/o function.
See minimal .zshrc attached.


% su -l heinb
Password:
tosh% emacs

zsh: suspended  emacs
tosh% bg
[1]  + continued  emacs
tosh%
[1]  + suspended (tty output)  emacs
tosh% jobs -l
[1]  + 20708 suspended (tty output)  emacs
tosh% fg %1
[1]  + continued  emacs
tosh% eclient
zsh: suspended  eclient
tosh% jobs -l
[1]  + 20718 suspended (signal)  eclient
tosh% bg
[1]  + continued  eclient
tosh% jobs -l
[1]  - 20718 running    eclient
tosh% fg %1
[1]  - running    eclient
<<<#### here terminal is broken


This is still even after 551ff842721d6ca83727dbe6cd40178f46cc8201
aka "43464: Another attachtty() fix."
