Review comment:
BTW (just a discussion not a code review comment): it can be useful to
differentiate between normalization (removing/resolving `..`, `//`) and
handling closing `/`. My impression is that we need different rules for them.
This is a good example here: you need the first ("normalization") but not
the second. (Maybe two different method?)
