1.0.11.3: belatedly recognizing STREAM-ERROR and PARSE-ERROR printing is OK

1.0.11.3: belatedly recognizing STREAM-ERROR and PARSE-ERROR printing is OK
	* (In my 1.0.9.60 patch, I fixed a READER-ERROR printing bug and
	  wrote that parallel PARSE-ERROR and STREAM-ERROR printing bugs
	  remained and that I would fix them. Now finally returning to
	  fix them, I find that they were fixed already, the tests work
	  with with no additional fixes needed.)
	* so I just un-#+NILed-out the tests
        * also made a few trivial rearrangements in
          src/code/condition.lisp, moving things around without changing
          meaning
