Using fgets() with a fixed-size buffer can lead to lines
being accidentally split across two calls if they are larger
than the buffer size.
As this is just a test helper, this is unlikely to be a
problem in practice. But since people may look at test
helpers as reference code, it's a good idea for them to
model the preferred behavior.
