All of them make sense, but I do not think we want to encourage that
loose style of passing unquoted argument to echo to lose embedded
$IFS spaces that is not a SP.

You mean dropping the quotes in the first patch?

Doing:

  echo "password=$(cat $HOME/.secret)"

already eats some trailing whitespace, though I guess if you have
newlines in your password you are beyond help anyway.

I can add back in the quoted \", though it does make the code slightly
harder to read.

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. :)
