Just the text of the panic messages is all that you can hope for in that
case.

There are also some bugs in the details:
- the file and line are not printed in panicstr
- the file and line are printed on a separate line
- some style bugs, starting with duplicating code to print the line numbers
  in the newpanic and !newpanic cases despite the previous 2 bugs making
  the message about the line numbers being independent of newpanic.
