4// returns [root, stripped]
5// Note that windows will think that //x/y/z/a has a "root" of //x/y, and in
6// those cases, we want to sanitize it to x/y/z/a, not z/a, so we strip /
7// explicitly if it's the first character.
8// drive-specific relative paths on Windows get their root stripped off even
9// though they are not absolute, so `c:../foo` becomes ['c:', '../foo']
