Yes, I know all that; what I meant by `tests' was internal shell tests as
opposed to external programs or other commands. Here's a simplified example
of what I'm seeing.
TRAPZERR () { echo exit code $?; }
chpwd () { [ -h $PWD ] && echo symlink; true; }
When I change to a directory that's not a soft link, I'm getting the `exit
code' message from 3.1.7-pre-1, whereas I never have with earlier versions.
I'm just wondering which way is correct, or are all versions correct and I'm
just missing out on understanding something else that's related?

Thanks, `trap - ZERR' is really what I meant to do all along, i.e. affect
only local behaviour inside the function, not global.
