I just double-checked it, and the above works for me. <shrug>

Thanks for doing that. I had planned to do it myself to avoid making
work for you, but what you posted looks good.

I hadn't thought about tty issues. You'd have to run it under
test_terminal (which isn't even available everywhere). So your
test-config version is probably the best bet.

I never noticed that before, and I agree that it's nonsense. Using "-p"
should be unnecessary if you have pager.foo defined (because it already
implies "yes, use the pager"). But if you were to do it anyway, I agree
it should not ignore the configured pager. One might use an extra "-p"
hoping that it would override the tty check, but it doesn't. It's too
late to change that now, I think, but I have been tempted to add a
--paginate-me-harder option. It would be handy for tests.
