   How unfortunate.

   BTW, http://www.kornshell.com/doc/ksh93.html claims ksh93 still has
   the old behavior:

     Improved debugging

     KSH-93 can generate line numbers on execution traces. Also, I/O
     redirections are now traced. There is a DEBUG trap that gets
     evaluated after each command so that errors can be localized.
