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.
