Re: [PATCHv2 0/13] credential helpers

It works, and it detects truncated output both ways properly (I know
because I had to update every test, since the old output was missing the
end-of-credential marker).

It makes me a little sad, because the original format (relying on EOF)
was so Unix-y.

It saddens me, too.  A reasonable middle ground would be to stop treating
an empty input as "no restriction" but "never matches".

I suspect that it is far more likely for a helper to fail (due to
configuration errors, for example) before it produces any output than
after it gives some but not all output lines.
