Calling getDirectory with undefined should return same dir

[Sebmaster]

Not sure if that's intended as-is, but when calling getDirectory with undefined in chrome, chrome calls the callback with the same DirectoryEntry on which getDirectory was called on.

Calling getDirectory with undefined is probably always a bug, in order to be in line with chrome the shim should follow it's behaviour though, not sure which way is better.

Agreed. It should do what the specs says. If the spec doesn't have answers, turn to Chrome's implementation :)

I couldn't find any exact specification in the W3C definition.

It says Otherwise, if no other error occurs, getDirectory must return a DirectoryEntrySync corresponding to path. though, not sure if undefined as argument is an error.
