Ghost in the friendly and interactive shell (fish):
I removed a `set -x VARNAME ...` line from my fish config.
Spawning a new shell still had that variable.
I ran `set -e VARNAME`. For the current shell, it's gone.
Spawning a new shell again, I got it back. What..?
Okay, so I closed _all the fish instances_.
And the damn env var came back *again*!?!
Looks like that's because it's my login shell.
A fresh login session no longer had it.
