    bin/sh               eval.c sh.1 var.c var.h 
  Log:
  Implement the PS4 variable which is defined by the POSIX User Portability
  Utilities option.  Its value is printed at the beginning of the line if tracing
  (-x) is active.  PS4 defaults to the string "+ " which is compatible with the
  old behaviour to always print "+ ".
  
  We still need to expand variables in PS1, PS2 and PS4.
