Looks very reasonable to me. Indeed, this line comes from 6adcca3fe8
(Fix initialization of a bare repository, 2007-08-27) which predates
2caf20c52b (test-lib: user-friendly alternatives to test [-d|-f|-e],
2010-08-10) when these helpers were originally introduced.

I thought that we could probably just shorten this to calling
"test_path_is_file" twice: once for "$1/config" and a second time for
"$1/refs", but that assumes "$1" is non-empty. And to ensure that you'd
need another check, which amounts to the same amount of code overall.

So the fix here looks good to me, and thanks for your contribution!

Thanks,
Taylor
