Subject: [PATCH] testdata: make tiny.txt simpler and faster

By avoiding the fmt import, we save some work: 'go test -run Script/tiny'
goes down from 0.8s to 0.5s even with a warm build cache.

Since the output changes between runs, we use stderr grep lines instead
of cmp. This way we can also check that the "oh noes" panic is entirely
hidden in the tiny mode.
