Thanks; this version makes all of those tests more readable. I did have
one idle thought while reading, but what you wrote is right (so I'm just
thinking out loud as opposed to anything else).

On my first read, I worried that this 'cat >>expect' when we're in
SHA-1 mode would append to the 'expect' we generated a few lines up. But
it doesn't, since we redirect the output of the 'if' statement into
'expect' instead of doing the redirect attached to the echo.

Subtle, but that's right. Good.

Thanks,
Taylor
