Neat idea, but when that shell exits, the PWD is back to where you
started.  The effect is the same as 

$ su
$ cd /root/hidden
$ exit

I can do this, however:

sudo sh -c 'cd /root/hidden && ls'

which gives me a listing of the directory and then exits.  That looks to
be the only workaround.  This all seems like a lot of effort to go
through just to avoid doing su . . .

Thanks for the ideas, Osamu.
