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.

1974986a82 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.

fd50df303c Put the description of the -c option in the right place, as
promised by the Argument List Processing section introduction.
What follows the option in the options list is its long name,
not its argument (as is the case for the -c option).  Also
sort references in the SEE ALSO section.
