e9aab1737b Document the ulimit -p option in the sh(1) manual page. 
When I imported the MPSAFE TTY code, I added the -p flag to sh(1)'s
ulimit, but I forgot to document it in the appropriate manual page.

7819e9ab69 Add the POSIX option -p to the jobs builtin command. It prints the PID of the 
process leader for each job.  Now the last specified option for the output
format (-l, -p or -s) wins, previously -s trumped -l.

40616c7bb3 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.

5c1966823e Add the times builtin. It reports the user and system time for the shell 
itself and its children.  Instead of calling times() (as implied by POSIX) this
implementation directly calls getrusage() to get the times because this is more
convenient.
