I'm no credentials-expert, but api-credentials.txt says this:
"Credential helpers are programs executed by Git to fetch or save
credentials from and to long-term storage (where "long-term" is simply
longer than a single Git process; e.g., credentials may be stored
in-memory for a few minutes, or indefinitely on disk)."
So the calls to approve/reject probably do matter in some scenarios.
The current code is a bit non-obvious as we just discovered since it
duplicates the strings (for good reasons, I believe) and then still
refers to the originals (also for good reasons, I believe). I suppose
your new function could be called like
server_fill_credential(&cred, srvc);
That should limit the impact of the change, but I'm not sure it's a
brilliant interface. Just my 2c.
