I get the same behavior from bash-3.2.48 and bash-4.0: canonicalizing ""
(since it's not an absolute pathname) results in $PWD, and the cd has no
effect.  If you run cd -P "" to avoid canonicalization, you get an error.
Make sure you're running `builtin cd' when you test to avoid the effect of
any function you've defined.
