FWIW, the code looks OK here. It is a shame to duplicate the policy
found in git_config_parse_key(), though.
I wonder if we could make a master version of that which canonicalizes
in-place, and then just wrap it for the git_config_parse_key()
interface. Actually, I guess the function you just wrote _is_ that inner
function, as long as it learned about the "quiet" flag.
