 PR bin/45390 - fix for folly four
 
 In the pwd builtin, verify that curdir names '.' before
 simply printing it.   Never alter PWD or OLDPWD in the
 pwd command.
 
 Also while here, implement the (new: coming in POSIX, but has existed
 for a while in several other shells) -e option to cd (with -e, cd -P
 will exit(1) if the chdir() succeeds, but PWD cannot be discovered).
 cd now prints the directory name used (if different from that given,
 or cdprint is on) if interactive or (the new bit)in posix mode.
 
 Some additional/changed comments added, and a DEBUG mode trace call
 that was accidentally put inside an #if 0 block moved to where it
 can do some good.

 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.
