Fabian Homborg a6a1c6e775 Port read tests to expect
Note: This includes a super cheesy thing to print variable contents.
The expect version has one that's a bit more elaborate (featuring a
marker setup), but tbh that doesn't seem to be worth it.

If we do need it, we can add it, but it seems more likely we'd just do
`set -S`, or do it in a check instead.

# to read from /dev/stdin when that is associated with the tty. These tests
