  This patch fixes a multibyte character boundary condition handling
  bug in ksh. This problem happens only when MB_CUR_MAX of the
  multibyte locale is greater than 2 and a 2-byte character is divided
  into two parts on a 1024-byte block boundary.  In this case,
  additional bytes may be skipped leading to incorrect execution of the
  ksh script.

  This patch fixes two ksh problems.
  1. ksh command line editing may not work correctly in emacs mode when the
     LANG environment variable is set to a multi-byte Asian locale.
  2. ksh script may crash if the script changes the LANG environment
     variable to a multi-byte Asian locale.
