Stefan Farfeleder 120c8e6c34 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. PR: 46441 (part of) Submitted by: schweikh Obtained from: NetBSD		2006-06-15 07:00:49 +00:00
