I thought about it. Here is where we get stuck:
usr/local/../../.. has to return ..
Yuck. If it an absolute path like /usr, you are fine.
In my first attempt, I counted the number of ".." groups, then went up
to remove each "..", and them remove a regular directory for each "..".
And then you have this case:
/usr/local/../bin/../..
Here you hit the first ".." as you are going up. It just seemed like a
lost cause.
