Multiple-guess question 19 says "Assuming that [...] a/. is not resolved
to be the same as a".
This clause was meant to be interpreted textually; that is, the lookup
routines contain no special-case code for "." (or "..").
"a" and "a/." do still (normally) refer to the same inode.
Also, "b does not" should be read "b does not exist".
