That does not have to be the case; I imagine most people would put
credential.helper in their ~/.gitconfig.
But I'm not sure I understand how that is relevant. The config subsystem
should work just fine whether we are in a repository or not (and if not,
return results only from system and user-wide config).
This probably _does_ trigger setup_git_env() when it was not otherwise
called, and it will back to looking at ".git/config" for the repo-level
config. That may fail to find the file if we are in a bare repository,
or a subdirectory of the working tree. IOW, I suspect this:
git init --bare foo.git
cd foo.git
git config credential.helper cache
git config credentialcache.ignoreSIGHUP true ;# goes into local config
git fetch https://example.com/foo.git
may fail to respect the ignoreSIGHUP option.
I guess the solution would be to setup_git_director_gently() in the
daemon process.
