A space is printed before the value in the repl. This throws off the first line of a trace. Could you get rid of that space?

~ (trace length) (length)

~ (length '(a b c d e)) |(length (a b c d e)) | (length (b c d e)) | |(length (c d e)) | | (length (d e)) | | |(length (e)) | | | (length ()) | | | 0 | | |1 | | 2 | |3 | 4 |5 5

~ (untrace length) (length)

~ (length '(a b c d e f)) 6

Ironically, it's actually the change that allowed the trace to print one line at a time that broke this in the first place. Yes, it should be fixable.
