cd0a6973f8 Make the cd builtin accept and ignore -P, which is a kshism that has been 
allowed to leak into POSIX and selects the behavior cd already implements.
Closes PR bin/42557 and also relevant to PR pkg/42168.

I suppose this should probably be pulled up to both -4 and -5...

the current directory doesn't exist.

e60beff86b Don't change the name of the directory we are going to 'cd' to just because 
we decide to remove a leading "./" when deciding whether to print the name.
Stops 'cd .//tmp' ending up the same as 'cd /tmp'.
Fixes PR/30735

8c772bc707 Don't apply CDPATH if the the first component of the target is "." or "..". 
Fixes PR/30973 and applies the principle of least surprise.
Update documentation to match (including date).
(matches behaviour of pdksh - if not it's documentation)

are connected to a tty:

	2. print directory on directory change.

296844fe72 Posix requires that 'pwd -P' reset the shells saved cwd value - so a 
subsequent 'pwd -L' will report the same value.
Update man page to be a closer match to reality.

df5bd11fb9 Validate the arguments to 'pwd'. Treat -L and -P as per pwd(1). 
Note that 'pwd -L' and 'pwd -P' almost always report the same answer as
the shell detects when 'cd' follows a symlink and discards its cached 'pwd'

c02b3bbdf4 Fixes from David Laight: 
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
  (so I could unset -e PS1 before running the test shell...)

5678a13f1b Re-introduce some code from 1.14 (with modifications) to make the 
shell's idea of the current working directory match reality when
symlinks (or anything else we can't stat) are traversed with the
cd command. However, this does not print out the cwd after cd
traverses symlinks, as it used to, though the capability is still
there should one want to use it.
