Just remember that in this case, the final "cd .." is not performed.

That may or may not matter to you.  As I mentioned, in UNIX systems it's
basically a no-op since the working directory is a property of each
individual process.  I don't think that's true in Windows, so omitting
the final "cd .." might cause issues.
