The convention in git.git is to avoid explicit NULL checks. So maybe
something like this, which also avoids the assignment inside an "if"

    key = getenv(envvar.buf);
    if (!key)
        break;

I think we should have a bit more complete tests of what happens if you
clobber existing config keys, and testing that this is set last after
system/global/local config.
