 Log Message:
 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.
