Log Message:
PR bin/45390

Be explicit about what happens to PWD after a successful cd command.
Also be very clear  that "cd" and "cd -P" are the same thing, and
the only cd variant implemented.

Also, when it is appropriate to print the new directory after a cd
command, note that it happens if interactive (as it always has here)
and also if the posix option is set (for POSIX compat, where "interactive"
is irrelevant).  Mention that "cd -" is a case where the new directory
is printed (along with paths relative to a non-empty CDPATH entry,
and where the "cd old new" (string replacement in curdir) is used.

While here document the new -e option to cd.
