I have recently been working (unavoidably) with recursive lists.  I set
print-length to a small enough number that the recursive parts of the lists
are not printed when evaluating expressions, etc.  Unfortunately, the
debugger resets print-length (as a fluid variable) to 50, so if recursive
lists are being passed to functions the backtrace cannot be printed.  The
fix is to set print-length to `(or print-length 50)' in (debug).

There's another problem with print-length.  If one invokes the
byte-compiler while it is set, then the functions are written out as
	(defun a-little-too-terse nil (interactive) ...)
I think it's arguable that the byte-compiler should reset print-length
to nil.  I also suspect that print-length should be reset in other places.
Or is it the responsibility of whoever sets print-length to reset it when
appropriate?
