new check-expect output with large values is hard to read
Consider this program
#lang htdp/asl
(check-expect (build-list 20 (lambda (x) x))
(build-list 21 (lambda (x) x)))
It prints:
[samth@huor:~/sw/plt (master) plt] raco test /tmp/d.rkt
raco test: (submod "/tmp/d.rkt" test)
Ran 1 test.
0 tests passed.
Check failures:

which is not great in a window that wraps, such as almost every terminal.
It's on my radar, but I'm unsure of a good strategy. Just dropping the boxes is probably not going to work, since test-engine's output (and the translations, and, and ...) all assume alignment.
One possible strategy would be to format the values with limited width.
Suggestions welcome!
When the values are long, just putting them on separate lines and then pretty-printing with limited width would be great.
