 	src/bin/sh: cd.c
 
 Log Message:
 PR standards/59565 - cd "" is now an error, not == cd .
 
 POSIX 2024 requires that cd "" generate an error message,
 and fail.
 
 Until now shells (including this one) have typically equated
 it to "cd ." as in the distant past, a lookup of "" as a path
 name would return the current directory (aka ".").
 
 From now on, we generate an error, as specified.
 (For this commit, the error message is kind of pathetic,
 but it is at least there - that will be fixed in a
 subsequent commit.)
