This is a little complicated by the way windows CD works.

Among other things, you can CD to a directory name with spaces
without quoting the name, as you would for most other commands.

It does seem that

CD . ..

does nothing, and generates no error message.
(I don't have a directory named ". ..")

CD . .. Q

(when Q is the only subdirectory)

fails with an error message.

But yes, if more than one matches the pattern, it does
change to the first one with no message.

(Unlike unix shells, where cd complains if there is more than one.)
