Or did you mean passing $1 in the test call? It definitely isn't good
shell practice, but we know that we're getting a single-word action from
Git, per the protocol.
Fully quoting, it looks like this:
helper = "!f() { test \"$1\" = get && echo \"password=$(cat $HOME/.secret)\"; }; f"
which IMHO is getting a little hard to read. I think that's part of why
I gave such an unfinished example in the first place. :)
