"credential.helper" was certainly what I'd intended, but I see the same behaviour with both options.

(I'd initially thought this was specifically due to the blank argument, hence the email subject which I clearly failed to update, but it looks like the issue occurs when using `-c` to set a config option regardless of the option being set.)

I've not tried to do any exhaustive testing, but I see this behaviour with "git fetch", "git pull", "git bisect" and "git submodule"; I see things apparently working as expected "git blame", "git commit", "git push", "git reset", "git switch" and "git log".
