Issue #1334
The problem was that there were too few slashes. On Linux, absolute
paths start with /, so
file:// + /home
gives file:///home, which is a valid path. On windows however, absolute
paths start with a drive letter, so
file:// + C:/Users
gives file://C:/Users, which is parsed as "host C, path Users", which is
why it could be written as file://c/Users (strip out the empty "port"),
giving us an invalid path.
The solution is to add the third slash in the template, and strip the
redundant slash on unix systems.
Additionally, this fixes a bug where navigating from '/home/' to the
parent directory would give '/home' instead of '/'
